dab131b1f8 Start enforcing /system file labeling
system_file_type is an attribute assigned to all files on the /system
partition. Add a compile time test to ensure that the attribute is
assigned to all the relevant types.

Test: code compiles.

5e37271df8 Introduce system_file_type
system_file_type is a new attribute used to identify files which exist
on the /system partition. It's useful for allow rules in init, which are
based off of a blacklist of writable files. Additionally, it's useful
for constructing neverallow rules to prevent regressions.

Additionally, add commented out tests which enforce that all files on
the /system partition have the system_file_type attribute. These tests
will be uncommented in a future change after all the device-specific
policies are cleaned up.

Test: Device boots and no obvious problems.

1b8284444c Assert types labeled in genfs_contexts have correct attributes
Types in sysfs should have the sysfs_type attribute, types in
debugfs and tracefs should have the debugfs_type attribute.

TODO: Test that files in procfs have the proc_type attribute.
TODO: Assert these tests in CTS.

370a52fee5 Improve data separation test coverage
Two areas need better coverage:
1. Tests are not verifying that files in /data/vendor do not have the
core_data_file_type attribute.
2. No error is thrown if a type lives in both /data/vendor
/data/<not vendor>.

Bug: 72998741
Test: build all selinux policies on master (assert build time tests)
Test: build and boot Marlin and Taimen, verify no selinux denials and
    everything works as expected.

afbcf21bfb Renames nonplat_* to vendor_*
This change renames the non-platform sepolicy files on a DUT from
nonplat_* to vendor_*.

It also splits the versioned platform sepolicy from vendor_sepolicy.cil
to a new file /vendor/etc/selinux/plat_pub_versioned.cil. And only keeps
vendor customizations in vendor_sepolicy.cil.

Build variable BOARD_SEPOLICY_DIRS is also renamed to
BOARD_VENDOR_SEPOLICY_DIRS.

ccf965e9ca Test that /data is properly labeled
Data outside of /data/vendor should have the core_data_file_type.
Exempt data_between_core_and_vendor for some types.

Ensure core_data_file_type and coredomain_socket do not get expanded
to their underlying types.

Test: build sepolicy for all targets in master (this is a build time
    test)
