On platform release T, the legacy `audio.a2dp.default` HAL no longer exists, and cannot be trivially restored for generic system-side A2DP audio support. Rather than trying to cling on to its existence (which does not even work anymore even if one did so), it is time to come up with a new solution. This commit introduces a system-side implementation of the generic bluetooth audio HAL. The HAL itself is modelled after the default bluetooth audio HAL, while substantial components of the default audio HAL are also included as it has to also implement the audio HAL interfaces. The audio HAL implementation is delegated to `audio.sysbta.default`, forked from `audio.bluetooth.default` from the Bluetooth apex package. It then communicates with the bluetooth audio HAL interfaces, which need to live in the same process (in this case, the process of the sysbta HAL). This is why we cannot just load `audio.sysbta.default` into the default audio HAL or the audioserver process directly, but rather have to include our own simplistic audio HAL implementation. For now, the audio HAL implementation only includes one for the 6.0 version, but technically, an interface for *every* audio HAL version needs to exist. This, along with other messiness in the sysbta implementation, will be addressed in a future commit. Note that to actually make use of the sysbta audio hal, patches in frameworks/av and packages/modules/Bluetooth are required to introduce support for the property `persist.bluetooth.system_audio_hal.enabled`.
