Bowgo Tsai 948934bae3 Separate system_ext_sepolicy.cil out of system sepolicy
Currently system sepolicy can be extended via:
  - BOARD_PLAT_PUBLIC_SEPOLICY_DIR
  - BOARD_PLAT_PRIVATE_SEPOLICY_DIR

To support having a single shared core system sepolicy, those
customization should be moved to the newly added system_ext partition.

System-ext-specific sepolicy files will be installed into
/system_ext/etc/selinux/*. system_ext_sepolicy.cil is merged into
precompiled_sepolicy at build-time. In case precompiled_sepolicy can't
be used (e.g. system-only-ota), the init will merge this file with
the rest of the sepolicy at runtime.

Bug: 137712473
Test: boot aosp_crosshatch with system_ext_sepolicy.cil
Test: boot aosp_crosshatch without system_ext_sepolicy.cil
