Camera: Remove old recording path support

With HALv1 now unsupported, remove recording codepaths that only it
needed
- Remove all support for metadata types besides ANWBuffer in CameraSource
- Remove now-unused Binder calls between camera service and CameraSource
- Delete code in record.cpp that was ifdef#0 anyway, and wouldn't have worked
  on Pixels for years

Test: atest android.hardware.cts.CameraTest && MediaRecorderTest && RecordingTest
Bug: 136024295
Change-Id: I87c4c32c1ebf1d0c39eaee15adc16b39c10525e8
