1c3d898d87 Add a neverallow for debugfs mounting
Android R launching devices and newer must not ship with debugfs
mounted. For Android S launching devices and newer, debugfs must only be
mounted in userdebug/eng builds by init(for boot time initializations)
and dumpstate(for grabbing debug information from debugfs). This patch
adds a neverallow statement that prevents processes other than init
from being provided access to mount debugfs in non-user builds
when the flag PRODUCT_SET_DEBUGFS_RESTRICTIONS is set to true.

Test: make with/without PRODUCT_SET_DEBUGFS_RESTRICTIONS

c8aa1bba0b Fix missing dependency in sepolicy mapping file rules
The system_ext_mapping_cil_$(ver) and product_mapping_cil_$(ver) rules
use build_sepolicy, but are missing a dependency on the tool.

8ada8a7c1b Support building mixed versions of sepolicy
Now newer system policy and older vendor policy can be built together by
setting following variables:

- BOARD_SEPOLICY_VERS
- BOARD_REQD_MASK_POLICY (copy of older system/sepolicy/reqd_mask)
- BOARD_PLAT_VENDOR_POLICY (copy of older system/sepolicy/vendor)
- BOARD_(SYSTEM_EXT|PRODUCT)_(PUBLIC|PRIVATE)_PREBUILT_DIRS (copy of
  older system_ext and product policies)

Bug: 168159977
Test: try normal build and mixed build
Test: boot and check selinux denials
