This CL is part of a refactoring work to unblock other CLs
that would generate a circular dependency when including
modules/audio_processing. It will also allow to easily move
the APM interface part under //api.
More in detail, this change adds a dummy build target named :api
in modules/audio_processing. It is needed to adapt the downstream
projects before the APM interface files are moved to the :api target.
A follow up CL will make :api an actual target and will remove
the interface files from :audio_processing.
