When building userdebug or eng builds, we still want to build the user
policy when checking neverallow rules so that we can catch compile
errors.

Commit c0713e86 split out a helper function but lost one instance of
using user instead of the real variant.  This restores that one and
adds it to the neverallow check.

Bug: 74344625
Test: Added a rule that referred to a type defined only
in userdebug and eng and ensure we throw a compile error when building
userdebug mode.

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.

Test: tested on walleye with PRODUCT_COMPATIBLE_PROPERTY=true
