Set the RTP Header Marker bit selectively per A2DP codec
Add a mechanism to set the RTP Header Marker bit per codec.
Currently, the Marker bit is set only for AAC.
Test: A2DP streaming, PTS AVDTP tests: TC_ACP_SRC_TRA_BTR_BV_01_C,
TC_INT_SRC_SIG_SMG_BV_17_C, TC_INT_SRC_TRA_BTR_BV_01_C

Add A2DP codec-specific information to dumpsys output
Now we print the following information:
* Current codec name
* Info for each supported codec:
- Priority
- Encoder interval (ms)
- Codec Config: Sampling rate, Bits per sample, Channel mode (MONO/STEREO)
- Selectable codec configuration
- Codec's local capability
- Packet counts (expected/dropped)
- PCM read counts (expected/actual)
- PCM read bytes (expected/actual)
* LDAC codec-specific info:
- LDAC quality mode: HIGH/MID/LOW/ABR
- LDAC saved transmit queue length [used in ABR mode]
* SBC codec-specific info:
- Frames counts (expected/dropped)
Sample of the new format is below:

Add a mechanism to configure the default A2DP codec priorities
Previously, the relative codec priorities were hard-codec internally.
The new mechanism uses the following configurable resources in
packages/apps/Bluetooth/res/values/config.xml to re-assign the
default codec priorities per device, or to explicitly disable a codec.
- a2dp_source_codec_priority_sbc
- a2dp_source_codec_priority_aac
- a2dp_source_codec_priority_aptx
- a2dp_source_codec_priority_aptx_hd
- a2dp_source_codec_priority_ldac
Those values are assigned on startup.
Also, they can be changed per device by using an overlay:
device/<VENDOR>/<DEVICE>/overlay/packages/apps/Bluetooth/res/values/config.xml
Test: Manually streaming to a headset

Integration of the aptX and aptX-HD codecs for A2DP source
Each of the codecs can be used if the corresponding encoding
shared library is installed on the device:
- aptX: libaptX.so
- aptX-HD: libaptXHD.so
Test: A2DP streaming to aptX and aptX-HD headsets
