Remove dependencies on hardware/audio_effects.h and EffectsFactoryApi.h

Also remove some outstanding dependencies on hardware/audio.h.

Most of the time, only constants and structs from audio_effects.h
are used, and no actual calls into HAL are made. Move these
definitions into system/audio_effect.h, and generate constants
from TREBLE HAL definition.

For parameters, always use values from AudioParameter class.

There are still some outstanding includes of hardware/audio.h
in code that directly deals with audio modules. Need to extend
libaudiohal interfaces to support required functionality.

Test: make
