For now, persist.rcs.supported has only vendor-init-settable, but it
turned out that the property should be read by vendor components in
some devices including 2018 Pixels.

persist.sys.zram_enabled is set in vendor/build.prop in taimen and walleye,
which was added after the initial whitelist.
go/treble-sysprop-compatibility requires whitelisting such a property to
allow it to be overridden by vendor/{default|build}.prop.

This CL lists all the exported platform properties in
private/exported_property_contexts.

Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.

Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.
