Add audio attributes info when starting aaudio tracks on MMAP mix.

In aaudio, when adding tracks to mixed stream, it is needed to update
audio attributes to HAL whenever the tracks are added or removed.
Currently, only the audio attributes used to open the stream will be
sent to the HAL. In that case, adding audio attributes of the clients
when starting the stream can help solve the problem. In audio flinger,
the client's audio attributes will be used to create MmapTrack.

Test: play multiple aaudio tracks, add log
