Modify ACodec to allow using Treble.
ACodec will connect to the Treble version of Omx if the property
"debug.treble_omx" is set to true ("1", "y", "yes", "true" or "on").
Also, fix some bugs found so far.
Test: Compiles

Implement client code to use Drm and Crypto HALs
This change adds DrmHal & CryptoHal classes that connect to the Treble
HAL interfaces for drm. These classes mirror the existing Drm and
Crypto classes that connect to the DrmPlugin and CryptoPlugin
interfaces. Having both allows mediadrmserver to run in either mode
while the HAL is stabilized.
The shared memory interfaces between mediaserver's ACodecBufferChannel
and ICrypto had to be reworked to use the Treble HALs. Specifically,
the shared memory path for returning decrypted buffers in the
non-secure case had to become separate instead of piggy-backing on the
source shared memory buffer. A separate shared memory destination
buffer is now allocated on the buffer channel. An abstraction for a
decrypt destination buffer was also introduced to clarify ICrypto's
decrypt method.
Tests: Playback using Play Movies and ExoPlayer works on angler
with and without the treble hal enabled.

stagefright: reuse buffers instead of cloning
In buffer array mode, the buffer reference is kept in clients of
MediaCodec, so allocating new buffer for new input/output does not
work in that case.

Bug: 32579231
Test: use screenrecord and investigate the output file.

MediaCodec refactoring part 1-c: buffer ownership
- Buffers are (roughly) owned by themselves.
- As a corollary, remove output format change related events
and replace by inspecting formats associated with each buffers.

Test: gts-tradefed run gts -m GtsExoPlayerTestCases
Test: (manual) Run Play Movies app to play a secure content.

MediaCodec refactoring part 1-b: secure buffers
- Define SecureBuffer to encapsulate secure buffers containing
decrypted data.
- ACodec and MediaCodec use SecureBuffer to communicate between
themselves.
Bug: 32133435
Test: Play an encrypted content in Play Movies

MediaCodec refactoring part 1-a: buffers become separate class
MediaCodecBuffer is meant to replace ABuffer and MediaBuffer in
communication between framework components. As the first step, replace
use of ABuffer in MediaCodec with MediaCodecBuffer, and adjust related
classes accordingly.
MediaCodec.getBuffer() and related APIs now returns MediaCodecBuffers;
thus change MediaCodec clients to use MediaCodecBuffer accordingly.
Test: manually tested for key use cases (Camera, YouTube and Play Movies)
