Treble sepolicy tests check whether previous versions are compatible to
ToT sepolicy or not. treble_sepolicy_tests_for_release.mk implements it,
but it also includes a compat test whether ToT sepolicy + {ver} mapping
+ {ver} plat_pub_versioned.cil can be built together or not. We
definitely need such tests, but we already have a test called "compat
test" which does exactly that, and testing it again with Treble sepolicy
tests is just redundant. The only difference between those two is that
Treble sepolicy tests can also test system_ext and product compat files,
which was contributed by a partner.
The ultimate goal here is to migrate *.mk to Soong, thus merging these
two tests (compat, Treble) into one. As we've already migrated the
compat test to Soong, this change removes the compat test part from
treble sepolicy tests. Instead, the compat test will be extended so it
can test system_ext and product compat files too.
prebuilts/api/{ver}/plat_pub_versioned.cil and
prebuilts/api/{ver}/vendor_sepolicy.cil are also removed as they aren't
used anymore: vendor_sepolicy.cil is an empty stub, and
plat_pub_versioned.cil can be built from the prebuilt source files.
