Add dynamic stream default effects
Allows runtime modification of what effects should be default
attached to streams of different types/usages. The core functionality
was already in the AudioPolicyEffects system, this allows
the dynamic modification of the lists.
Bug: 78527120
Test: Builds, manually tested an app adding a stream effect,
tested both media on the specified stream and on a different stream.
Also tested by Android Things integration tests.
