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. Change-Id: Ib98aaba062f10972af6ae80fb85b7a0f60a32eee
