Subject: [PATCH 1/2] Porting LE Audio unciast on F10.

1. Default enable LE Audio unicast on android U.
2. Enable LE Audio offload flag
3. Add the offload capability file for unicast
4. Enable LE Audio switcher flag(for developer option)
5. Enable BQR event mask for LE Audio choppy event

Bug: 273167787
Test: LE Audio unicast related services are all enabled by default
Test: Media & Phone call can stream via LE Audio SW/HW path
