Use lint database from api_version_public

These two databases are (nearly) identical but the latter is generated
in a much more efficient way.

The diffs are very minor and it's not clear to me which versions is more
correct than the other, though I'm fairly confident they don't matter.

Droidstubs now support using the api-versions.xml from another
droidstubs module, so reuse the one from api_versions_public
in framework-doc-stubs.

Bug: 187398174
Test: diff api-versions.xml
Test: diff stubs of framework-doc-stubs
