Previously, we always used ImageReader to read from the output of DefaultVideoFrameProcessor, for pixel tests. This has a limitation of not being
able to read HDR contents, so that we couldn't support HDR pixel tests.
Reading from a texture allows us to use glReadPixels to read from
DefaultVideoFrameProcessor, and build upon this to implement HDR pixel tests. We do
still want tests for surface output though, because real use-cases only will output
to Surfaces.
Also, add some tests for outputting to textures, since this test infrastructure is
a bit complex.

This change makes sure that live ad periods that are played are
skip when attempted to be added to the queue. To make this work
the existing filter logic had to be take into account the content
resume offset that live periods use.

This change makes sure that the `AdPlaybackState` of any period can
contain an empty postroll placeholder.
The placeholder postroll should be represented in the `MediaPeriodId`
of a content period as `nextAdGroupIndex`, but should be ignored when
building the list of `MediaPeriodInfo` in the `MediaPeriodQueue`. This
is required to allow to add an ad group to ad playback state of the
content period that is currently being played, instantly insert an ad
period into the media period queue and immediately transition playback
to the new period.
This change makes sure and tests that
- a live server side inserted postroll placeholder can be inserted to
a `AdPlaybackState` in well-defined and tested way (helper method)
- a postroll placeholder is NOT ignored when
`AdPlaybackState.getAdGroupIndexAfterPositionUs` is called (this
is required when evaluating the `nextAdGroupIndex`).
- a postroll placeholder is ignored when
`AdPlaybackState.getAdGroupIndexForPositionUs` is called (this is
required to not attempt to play the ad and is analogous to ignore the
post roll placeholder in a single period timeline).
- `MediaPeriod.getFollowingMediaPeriodInfo()` does not include a
`MediaPeriodInfo` for the placeholder postroll when building the
queue.

This timeline will be used in unit test cases of follow-up
CLs. It basically can be used to emulate the timeline created by a
multi-period live media source when the real time advances.

Following test cases are added:
1. Mux H264 video
2. Mux H265 video
3. Mux HDR video
Each test case performs following actions:
1. Extract track and samples from input Mp4 using MediaExtractor.
2. Feed those samples into Mp4 muxer.
3. Use extractor to extract the samples from muxed file and create dump file.

In most cases, this means updating Subject subclasses and their assertThat methods to accept null actual values. (They should always accept null so that assertions like "assertThat(foo).isNull()" succeed instead of throwing NullPointerException.)
Occasionally, it involves other changes, like writing `isGreaterThan(1L)` instead of `isGreaterThan(1)` to resolve an ambiguity it Kotlin overload resolution.
PiperOrigin-RevId: 511776581
Otherwise, a lack of HDR decoding support will result in the tests checking output files for HDR output, like HdrEditingTest.transform_noRequestedTranscode_hdr10File_transformsOrThrows, failing.

GLEffectsFrameProcessor, MatrixShaderProgram and FinalMatrixShaderProgramWrapper are currently setup to handle the input frames coming from an external input (i.e. a video decoder). Image input is loaded into Bitmap objects at the start of the pipeline, so they are not produced externally. The changes provide a way for the frame processing pipeline to handle this "internal" (i.e. non-external) input.

Based on [this conversation thread](https://chat.google.com/room/AAAA--f88ao/76Rem_cRCK8), I've opted to update the existing FrameProcessor.create() rather than deprecate it, as it is unlikely to be in use by apps outside google3.

Add checks to GL tone-mapping pixel tests, to ensure the device's decoder, API
version, and OpenGL implementation support GL tone-mapping before attempting it.
These tests should be run on mobile harness, to detect per-device failures, and
so are moved to transforemr/mh. Per b/263395272, these tests should ultimately
be in an effect/mh directory.

Also, omit the "actual" label from output files, as this boilerplate isn't necessary
(it doesn't disambiguate between any other saved filename like "expected").

Frame cache compensates for the fluctuation in frame processing times.
Imagine a frame takes 10ms to process, and the interval between two frames is
33ms. The third frame took 40ms to process.
If we don't have frame cache:
- Process frame 1, ready after 10ms, starts playback, now t=0 ms
- Start processing frame 2, ready at t=10ms,
- Release frame 2 at t=33ms
- We start processing the third frame at t=33ms
- The third frame is due presentation at t=66ms
- But frame 3 is available at t=73ms, late
If we have a frame cache of say 3 frams,
- Process frame 1, ready after 10ms, starts playback, now t=0 ms
- Start processing frame 2, ready at t=10ms
- Start processing frame 3, ready at t=50ms
- Release frame 2 at t=33ms
- Start frame 4, ready at t=60ms
- Frame 3 is due presentation at t=66ms
- Frame 3 isn't late

Move BitmapTestUtil from media3.effect to media3.test.utils.
This allows this class to be accessed from both transformer and effect tests.

BasePlayer simplifies implementations by handling all the various
seek methods and forwarding to a single method that can then be
implemented by subclasses. However, this loses the information about
the concrete entry point used for seeking, which is relevant when
the subclass wants to verify or filter by Player.Command. This
can be improved by adding the command as a new parameter. Since
we have to change the method anyway, we can also incorporate the
boolean flag about whether the current item is repeated to avoid
the separate method.

These have the same value (`-1`), and basically the same meaning (offset
in an array/list/file/byte stream/etc), but 'position' is an overloaded
term in a media playback library, and there's a risk people assume that
methods like `Player.getCurrentPosition()` may return
`C.POSITION_UNSET`, when in fact unset media times (whether duration or
position) are always represented by `C.TIME_UNSET` which is a) a `long`
(not `int`) and b) a different underlying value. (aside:
`getCurrentPosition()` never returns an unset value, but it's a good
example of the ambiguity of the word 'position' between 'byte offset'
and 'media timestamp'.)

FakeClock keeps an internal list of messages to be executed to
ensure deterministic serialization. The next message from the list
is triggered by a separate helper message sent to the real Handler.
However, if the target HandlerThread is no longer alive (e.g. when
it quit itself during the message execution), this helper
message is never executed and the entire message execution chain
is stuck forever.
This can be solved by checking the return values of Hander.post or
Handler.sendMessage, which are false if the message won't be
delivered. If the messages are not delivered, we can unblock the
chain by marking the message as complete and triggering the next
one.

Our FakeClock generally makes sure that playback tests are fully
deterministic. However, this fails if the test uses blocking waits
with clock.onThreadBlocked and where relevant Handlers are created
without using the clock.
To fix the flakiness, we can make the following adjustments:
- Use TestExoPlayerBuilder instead of legacy ExoPlayerTestRunner
to avoid onThreadBlocked calls. This also makes the tests more
readable.
- Use clock to create Handler for FakeVideoRenderer and
FakeAudioRenderer. Ideally, this should be passed through
RenderersFactory, but it's too disruptive given this is a
public API.
- Use clock for MediaSourceList and MediaPeriodQueue update
handler.
