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`.

Issue: androidx/media#220
PiperOrigin-RevId: 495642588

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.

The TransformationResult has some useful values that are set in error
cases, such as the codecs used.

PiperOrigin-RevId: 495568259

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

Adds COLOR_TRANSFER_GAMMA_2_2, to match behavior in other HDR to SDR tone mapping
implementations.

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.

This ensures they are not accidentally triggered again when
the state is rebuilt with a buildUpon method.

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.

This simplifies the caller slightly.

`SilentAudioGenerator` could output a fractional audio frame, and this could cause downstream components to throw because of trying to read a complete audio frame but only seeing a partial one.

Calculate the output buffer size based on the frame size (which is a no-op for stereo 16-bit audio) and calculate a total number of frames to output then multiple by the frame size.
