audio policy: fix playback permission checks
Align playback permission checks implementation in getOutputforAttr() on
capture checks in getInputForAttr(): use an "output type" returned by
audio policy manager and check permission accordingly.
- Do not modify but reject request to play to call uplink when permission
is denied.
- Add missing permission check for injection to remote submix.
- Clarify permission check for record from remote submix by using the
uid/pid of client explicitly.
Bug:
Test: CTS test for AudioTrack and AudioREcord.
Test: GTS tests for dynamic policies and playback capture
