Users of this class may run into these assertions when creating the
State and they need to check the source code to understand why
the State is invalid. Adding error messages to all our correctness
assertions helps to understand the root cause more easily.

This CL replaces concurrent collections and atomic primitives with a single
lock, this way the code is easier to reason about.

Note that we simply use GlEffectsFrameProcessor in-app / GL tone-mapping, so PQ->SDR tone-mapping isn't yet implemented.
Tested manually using the demo on Pixel 7, to confirm that device and in-app tone
mapping behave similarly.

Adds the AudioMixerAlgorithm interface which allows for specialized
implementations of audio mixing that also efficiently convert between
source and mixing formats.
Initial implementation has two algorithms:
1. Float -> float (with channel mixing)
2. S16 -> float (with channel mixing)

To do that, rename PROGRESS_STATE_NO_TRANSFORMATION to
PROGRESS_STATE_NOT_STARTED and update Javadoc of ProgressState to not be
Transformer specific.

This should allow us to focus on HDR failures instead of network buffering
failures when debugging HDR issues.
These files are each used on several files, so it should be more worth the
test binary impact to move these files to local first.
Locally, tests did take less time after this diff

The MediaSourceFactory won't be used by the other AssetLoaders
In order to do that, ExoPlayerAssetLoader has been made public, and the
DefaultAssetLoaderFactory has become a wrapper around
ExoPlayerAssetLoader.

These are the remaining setter operations. They all share the same
logic that handles playlist and/or position changes. The logic to
create the placeholder state is mostly copied from ExoPlayerImpl's
maskTimelineAndPosition and getPeriodPositonUsAfterTimelineChanged.

The period updates were introduced to ensure the buffered position is
updated regularly and that any playback position drift is corrected.
None of these updates need to happen while the player is paused or
not loading and we can avoid the constant binder interactions.

FrameProcessor already support using different transfer function for input and
output color. This CL has two major changes:
- Create an eglSurface that recognizes BT.2020 PQ
- This requires a separate extension that works only after 33
- So we current throw, if input is HDR, and this extension doesn't work
- Create FrameProcessor with PQ output transfer function

The tunneling callbacks are sent via Handler messages and may be
handled after the codec/surface was changed or released.
We already guard against the codec/surface change condition by
creating a new listener and verifying that the current callback
happens for the correct listener instance, but we don't guard
against a released codec yet.

Some Player methods operate relative to existing indices in the
playlist (add,remove,move,seek). As these operations may be issued
from a place with a stale playlist (e.g. a controller that sends
a command while the playlist is changing), we have to handle out-
of-bounds indices gracefully. In most cases this is already
documented and implemented correctly. However, some cases are not
documented and the existing player implementations don't handle
these cases consistently (or in some cases not even correctly).

The `MediaItem` instances in the following cases are not actually empty but acts as a placeholder. `EMPTY_MEDIA_ITEM` can also be confused with `MediaItem.EMPTY`.

Improves the time taken to construct `playerInfo` from its bundle from ~450 ms to ~400 ms. Each `MediaItem` inside `Timeline.Window` contains `MediaMetadata` and hence is a good candidate for bundling optimisations. There already exists a test to check all parameters for null values when unset.

It covers the following cases:
| From/To | `null` | `surface 0` | `surface 1` |
|-------------|--------|-------------|-------------|
| `null` | 🆖 | 📺 | 📺 |
| `surface 0` | ❌ | 🔁 | 📺 |
| `surface 1` | ❌ | 📺 | 🔁 |
Where
- 🆖 means NOP
- ❌ means
- Set `null` on FrameProcessor, effectively dropping all frames
- 📺 means
- Notify the listener of video size
- Set FrameProcessor output surface and size when MSG_SET_VIDEO_OUTPUT_SIZE is received
- 🔁 means
- Notify the listener of video size

This simplifies some position tracking needs for an app implementing
SimpleBasePlayer.
- The period index can always be derived from the media item index
and the position. So there is no need to set it separately.
- The media item index can be left unset in the State in case the app
doesn't care about the value or wants to set it the default start
index (e.g. while the playlist is still empty where UNSET is
different from zero).
- Similarly, we should allow to set the content position (and buffered
position) to C.TIME_UNSET to let the app ignore it or indicate the
default position explictly.

Otherwise, the decoders are not captured. It works at the moment for the
video decoder because decoding is still done on the sample pipeline but
it will moved to the AssetLoader soon.

`AudioProcessor`s expect direct buffers. This shouldn't make any functional difference in our code, but a custom audio processor might try to access the buffer from JNI in which case a direct byte buffer is more efficient.
