New maintenance scheme for mapping files:
Say, V is the current SELinux platform version, then at any point in time we
only maintain (V->V-1) mapping. (V->V-n) map is constructed from top (V->V-n+1)
and bottom (V-n+1->V-n) without changes to previously maintained mapping files.
Caveats:
- 26.0.cil doesn't technically represent 27.0->26.0 map, but rather
current->26.0. We'll fully migrate to the scheme with future releases.
Bug: 67510052
Test: adding new public type only requires changing the latest compat map

Private types are not visible to vendor/odm policy, so we don't need mapping
entries for them.
We build platform-only public policy .cil file and give it as input to
treble_sepolicy_tests. Using this public policy the test can now figure out if
the newly added type in public or private.
Bug: 116344577
Test: adding public type triggers mapping test failure, adding private type does
not.

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.

(cherry picked from commit 55d5e28472)
vendor_init exists on the system partition, but it is meant to be an
extention of init that runs with vendor permissions for executing
vendor scripts, therefore it is not meant to be in coredomain.

Bug: 37008075
Test: build, all tests pass. Modify some attributes locally to
cause tests to fail (verify that they are actually working).
