This adds support for the HEVC/H265 codec to the Android codec2 V4L2
decode component.
Bug: 215043150
Bug: 183217901
Test: ExoPlayer works with HEVC on guybrush w/ codecs added and
corresponding ChromeOS CLs for crosvm/libvda

This CL Move the V4L2 device and V4L2 device poller files to the common
code folder. In a next step these files will be cleaned up and reworked
into proper Android code, but splitting the move into a separate CL
makes the review process a lot easier.

Originally we use C2AllocatorBlob for linear allocator. Actually the
recommended linear allocator is C2AllocatorIon. The better way is to
use C2AllocatorStore::DEFAULT_LINEAR id, and choose C2AllocatorBlob
by setting the value of "debug.stagefright.c2-poolmask" at device.mk.

This CL removes unused variables at V4L2DecodeInterface, and uses the
correct picture size to calculate the size of input buffers.

InputBufferManager notifies the codec2 framework when the component no
longer has any references to an input buffer. While a dedicated release
notification is necessary in some circumstances, the release can usually
be done when the corresponding work item is completed, to reduce the
amount of IPC. This change sets the notification interval used by
InputBufferManager to reduce how often a dedicated release notification
is sent.

Every C2ComponentInterface would be initiated at Android bootup time.
We want to avoid heavy action in the interface initialization.
This CL relaxes the parameter check by using the maximum fixed number
instead of querying the capability from V4L2 device.

The V4L2 stateful API requires the caller pass the same buffers to the
output queue slot. Originally we use C2PooledBlockPool for byte buffer
mode, but C2PooledBlockPool cannot get buffer identifier.
This CL switches to use C2VdaPooledBlockPool, which guarantees to
return a fixed set of buffers and could query the buffer index.

In this CL, V4L2DecodeComponent supports the protected playback by
using C2VdaBqBlockPool. To use C2VdaBqBlockPool, there are 2 specific
requirements compared to a normal C2BlockPool:
1. Call C2VdaBqBlockPool::requestNewBufferSet() before fetching blocks
2. Call MarkBlockPoolDataAsShared() after creating C2ConstGraphicBlock

C2_PARAMKEY_OUTPUT_DELAY is the number of additional output frames
that needs to be generated before an output can be released by the
component.
H264 may reorder the output frames, so we set C2_PARAMKEY_OUTPUT_DELAY
to the possible maximum number of reoder frames.

This CL implements V4L2DecodeComponent, a decode C2Component via V4L2
API. It mainly contains these parts:
- VideoDecoder:
An interface for video decoding, similar to media::VideoDecoder at
Chromium project.
- V4L2Decoder:
An implementation of VideoDecoder via V4L2 stateful API. We wrap all
V4L2-related logic in this class
- VideoFrame
The data structure to represent the output buffer of VideoDecoder.
It encapsulates a C2GraphicBlock and only exposes the essential
information of physical buffers.
- VideoFramePool:
The buffer pool used by VideoDecoder. It encapsulates C2BlockPool
and provides asynchronous method to fetch buffers.
- V4L2DecodeComponent, V4L2DecodeInterface:
The C2Component implementation that delegates the decode request to
V4L2Decoder.
- V4L2ComponentFactory:
The C2ComponentFactory that creates V4L2DecodeComponent.
Bug: 152714603
Test: mmm external/v4l2_codec2/
Test: Run e2e test and make sure the V4L2DecodeComponent is running
