Decode-only video frames (needed when the frame at / first frame after the
clipping start is not a key frame) need to be decoded but not passed to
the frame processor chain or encoder.

The clipping start offset needs to be removed from the frame timestamps
in the passthrough and video pipelines.
There are no changes needed for this in the audio pipeline, as it doesn't
use the input timestamps -- it uses its own timestamps derived from the
buffer sizes instead.

Also add demo option to try this out.

There's no need to manually construct a 'default'
DefaultDataSource.Factory instance, we can just pass the `Context` to
`DefaultMediaSourceFactory` and let it construct the
`DefaultDataSource.Factory` internally.

Also update names of implementations to match design doc.
In follow-ups, SingleFrameGlTextureProcessor will become
an abstract implementation of a new GlTextureProcessor
interface.

Texture processor makes sense as it processes OpenGL textures.
The term frame processor will be used for something else in
follow-ups.

* Rename (via deprecation)
  `MediaItem.DrmConfiguration.Builder#forceSessionsForAudioAndVideoTracks`
  to `setForceSessionsForAudioAndVideoTracks`. This is more consistent
  with existing 'force' method names both in this class and in
  `TrackSelectionParameters.Builder`.
* Add missing `@Nullable` annotation to the parameter for
  `MediaItem.SubtitleConfiguration.Builder#setMimeType`. This annotation
  is already present on the `MediaItem.SubtitleConfiguration#mimeType`
  field that this setter corresponds to.

There is a problem with the ImageReader formats used by the
SSIM helper that only occurs for Nexus 5 API 21, so as a workaround
we can skip the SSIM calculation on Nexus 5 API 21.

This skips just the SSIM calculation (by setting the value to
1.0 instead and logging). The tests still run when SSIM is skipped
so that we can detect other failures.

Decoding and encoding 320x240 H264 video should be supported
on all devices from Android 5.0 based on CDD requirements.

640x360 encoding doesn't seem to be supported on Nexus 5.

Recreating an EGLSurface for a surface that already has an
EGLSurface is not allowed according to the
[documentation](https://www.khronos.org/registry/EGL/sdk/docs/man/html/eglCreatePlatformWindowSurface.xhtml).

This fix was tested on the devices listed in the bug
description (Pixel 5a, Nexus 5).

AudioTrack.setOffloadEndOfStream should be called after a track
has been buffered. Additionally, the AudioTrack must be playing.

It has been observed that for very short media (<1s), the AudioTrack
might not have started immediately after the read that buffered
the audio.

In such a situation, calling AudioTrack.setOffloadEndOfStream throws
and playback fails.

Avoid this failure by checking that the AudioTrack is playing before
calling setOffloadEndOfStream.

This means that very short gapless media will not be gapless, this was
deemed acceptable given that such very short media should be very rare
in offload.

Put cloud storage samples at the top to avoid having a sample at the top of the list where we don't control the server.

Also update labels not to mention progressive container type, as it's irrelevant for Transformer, which always transmuxes even if it doesn't transcode.

This detection relies on an unsupported workaround and may trigger
permission warnings in tools analyzing permission usage although
no permission is needed or requested by app code.

Given the majority of 5G-NSA playbacks are on API 31+ by now,
we can remove this path to avoid the permission confusion and the
unsupported detection workaround.

The debug surface view's output surface can become invalid during a transformation due to the parent activity pausing, for example. This can currently cause a crash when backing out of the `TransformerActivity` in the demo because the surface can be destroyed before the transformer has fully canceled.

Also clarify naming of the outputSurface and inline the private method that created `EGLSurface`s (it was shorter after removing the debug preview).
