Consolidate requiresSecureDecoder logic in ExoMediaDrm

This change:
1. Updates the implementation of
   `FrameworkMediaDrm.requiresSecureDecoder` to include the
   'force allow insecure decoder' workaround logic.
2. Removes the 'force allow insecure decoder' logic from MCR
3. Removes the `requiresSecureDecoder` field from MCR (it can just
   be a local derived from `codecDrmSession` now).
