Initial selinux policy support for memfd
Move all app tmpfs types to appdomain_tmpfs. These are still protected
by mls categories and DAC. TODO clean up other app tmpfs types in a
separate change.
Treble-ize tmpfs passing between graphics composer HAL and
surfaceflinger.
Bug: 122854450
Test: boot Blueline with memfd enabled.
