This change applies to standalone TTML files linked directly from the manifest.
As a result, we no longer have the flakiness in the DashPlaybackTest which uses sidecar-loaded (standalone file) TTML subtitles. We experimentally opt into parsing subtitles during extraction and use SubtitleExtractor in hybrid mode.

This CL adds an isPrioritizeImageOverVideoEnabled flag to
TrackSelectionParameters and an API to set the flag value.
The flag will be used by DefaultTrackSelector to determine whether
to select an image track if both an image track and a video track are available.

A few methods in PlayerInfo and related classes combine filtering
information with bundling in one method. This makes it impossible
to use just the filtering for example and it's also easier to reason
about than two dedicated methods. This change splits these methods
into two parts accordingly.

When used within the same process, we don't have to go via the
onTransact method (which includes marshalling and unmarhsalling
the data), but can directly return the list.

The flag is no longer used by our components and only set and checked
in a few places to guarantee compatiblity with existing renderers and
decoders that still use it.
The flag will be removed in the future due to its design limitations.

location and index are mostly equivalent, except that it's possible that location is more up-to-date than index, so we can just always use location.

The per-stream methods are generally preferred and having a reference
to them from the device-wide methods may help with discoverability.

Adjust the Javadoc to highlight that data of this MIME type just contains a URI, not the actual image content.
And also remove the superfluous "key" part of the MIME type string that doesn't
really add information (and it's also really just an URI, not an URI key).

Move audio offload mode related interfaces and definitions from `TrackSelectionParameters` to a new `AudioOffloadModePreferences` class.

This method isn't used by the library (since <unknown commit>).
It doesn't really work well (e.g. arbitrarily defaults to `MUSIC` when
`UNKNOWN` would be a better default). There's no suggested replacement.

This change introduces two new types of method to `SubtitleParser`:
1. `parse()` methods that take a `Consumer<CuesWithTiming>` and return `void`
2. `parseToLegacySubtitle` method that returns `Subtitle`
(1) ensures that in the new 'parse before SampleQueue' world we can
write cues to the `SampleQueue` as soon as they're ready - this is
especially important when parsing monolithic text files, e.g. for a
whole movie.
(2) ensures that during the transition, the legacy 'parse after
SampleQueue' behaviour doesn't see any regressions in 'time to first
cue being shown'. Previously we had a single implementation to convert
from `List<CuesWithTiming>` to `Subtitle`, but this relies on the
complete list of cues being available, which can take a long time for
large files in some formats (with ExoPlayer's current parsing logic).
By allowing implementations to customise the way they create a
`Subtitle`, we can directly re-use the existing logic, so that the
'time to first cue being shown' should stay the same.
This change migrates all **usages** to the new methods, but doesn't
migrate any **implementations**. I will migrate the implementations in
follow-up CLs before deleting the old list-returning `parse()` methods.

Previously any `CuesWithTiming.durationUs` could be `TIME_UNSET`,
meaning it should be replaced by the next `CuesWithTiming` instance
(instead of being merged if the durations overlap, which is currently
the expected behavior for all `CuesWithTiming` with a 'real' duration).
This technically allowed a single subtitle track to include a mixture of
`CuesWithTiming` that should be merged, and some that should be
replaced. This is not actually needed for any of the subtitle formats
currently supported by ExoPlayer - in all cases a format expects either
all cues to be merged, or each cue to replace the previous one.
Supporting this mixture of merging and replacing in `TextRenderer` ended
up being very complicated, and it seemed a bit pointless since it's not
actually needed. This change means a given subtitle track either merges
**all** cues (meaning `CuesWithTiming.durationUs = C.TIME_UNSET` is not
allowed), or **every** cue is replaced by the next one (meaning
`CuesWithTiming.durationUs` may be set (to allow for cues to 'time out',
needed for CEA-608), or may be `TIME_UNSET`).
This value will be used in a subsequent change that adds cue-merging
support to `TextRenderer`.

This is equivalent to the existing `scaleLargeTimestamp` method with the
following changes/improvements:
* No longer specific to timestamps (there was nothing inherently
time-specific about the logic in `scaleLargeTimestamp`, but the name
and docs suggested it shouldn't be used for non-timestamp use-cases).
* Additional 'perfect division' checks between `value` and `divisor`.
* The caller can now provide a `RoundingMode`.
* Robust against `multiplier == 0`.
* Some extra branches before falling through to (potentially lossy)
floating-point math, including trying to simplify the fraction with
greatest common divisor to reduce the chance of overflowing `long`.
This was discussed during review of 6e91f0d4c5
This change also includes some golden test file updates - these
represent a bug fix where floating-point maths had previously resulted
in a timestamp being incorrectly rounded down to the previous
microsecond. These changes are due to the 'some more branches' mentioned
above.

Instead of invoking "undefined behavior" may occur when a class is used
incorrectly, which is clear but not very helpful to callers, specify what Apps
or users of a class should do when issues occur.
Apply this to Compositor as well, where this otherwise might seem unclear.
