Add binderized context hub HAL

Browse Source 
Add context hub HAL implementation to the build, with new sepolicy files
that resolve these denials:

type=1400 audit(4779207.059:418): avc: denied { write } for pid=809
comm="android.hardwar" name="chre" dev="tmpfs" ino=32491
scontext=u:r:hal_contexthub_default:s0
tcontext=u:object_r:socket_device:s0 tclass=sock_file permissive=1

type=1400 audit(5568590.159:45): avc: denied { connectto } for pid=734
comm="android.hardwar" path="/dev/socket/chre"
scontext=u:r:hal_contexthub_default:s0 tcontext=u:r:chre:s0
tclass=unix_stream_socket permissive=1

Bug: 35808469
Test: confirm HAL gets loaded, VTS passes, no denials from
      hal_contexthub_default
