Expose permission MEDIA_RESOURCE_OVERRIDE_PID as a system API and allow 

vendor services to use it

The MEDIA_RESOURCE_OVERRIDE_PID permission is needed to create codecs on
behalf of other processes. The protection level is elevated to allow for
Vendor and OEM processes, specifically for Vendor/OEM TvInputService
which manages inputs for broadcast and cable TV apps.
