Split audio effects headers
There can be different use cases with the code that imports
headers from audio_effects (each subsequent case is a more
specialized version of the previous one):
1. The code only needs access to general structures
like effect_descriptor_t:
==> include system/audio_effect.h
Example: AudioSystem in libmedia
2. The code that needs access to effect UUID and parameter
enums:
==> include system/audio_effects/effect_foo.h
Examples: media framework effects interfaces, libwilhelm
3. The code that needs to call into HAL:
==> include hardware/audio_effect.h
Examples: libaudiohal (implementation part) and libeffects
4. The code that implements a particular effect:
==> include audio_effects/effect_foo.h
Examples: cts/.../CTSTestEffect.cpp
