audio: Provide code for parsing surround sound config from XML
The main change is to convert the result of parsing from XSDC
types to AIDL, and add a VTS test for IConfig.getSurroundSoundConfig.
Extra changes:
- add 'Unchecked' suffix to conversion functions that do not
wrap the result into ConversionResult;
- enable more compile-time checks for the default AIDL service,
fix issues found.
Bug: 205884982
Test: atest VtsHalAudioCoreTargetTest
Change-Id: Icf578b8d28647e6355ed5328599c77d2ca1234f9
