media: Implement CodecBase interfaces in ACodec

Some case will check AAC parameter "aac-profile" or "profile".
C2 AAC format include this parameter.
but OMX AAC format do not have this parameter, so add "aac-profile" for OMX AAC.

Some case will check media codec parameters interfaces,
but these interfaces do not implement in ACodec, so cases failed.
Implement these interfaces in ACodec.

Test: atest android.mediav2.cts.EncoderProfileLevelTest#testValidateProfileLevel
