Remove FrameworkSampleSource. 

ExtractorSampleSource covers almost all use cases (except for AMR, AVI and
legacy Widevine). The FLAC extension must be compiled for support for FLAC
extraction.

FrameworkSampleSource has device-specific issues, makes blocking calls to the
underlying MediaExtractor, and does not provide much control over buffering.
