Pass crypto source data using a shared buffer
MediaCodec was using a binder transaction buffer
to pass encryption source data for protected content.
On some 4K content, the max binder transaction buffer
size was being exceeded. This change uses a shared
buffer for the encryption source data instead of a
binder transaction buffer, which avoids the problem and
may be more efficient.
