Set/get allowed capture policy via AudioService.

Do not call AudioSystem.setAllowedCapturePolicy directly in
AudioManager. Instead, send the request to AudioService and calling the
function in AudioService. In that case, AudioService can cached the
request so that it benefits returning correct playback configuration.

When querying capture policy, AudioManager will query AudioService first
to see if there is cached capture policy. If there is exception, return
cached capture policy in AudioManager.

Test: dumpsys audio, query active audio playback configuration
Test: atest AudioManagerTest, AudioAttributesTest
Test: atest AudioPlaybackCaptureTest, AudioPlaybackConfigurationTest
