QtQml: Move locateLocalQmldir and make it a template

It conceptually belongs into QQmlImportDatabase because it messes with
the qmldir cache.

This way, if we reject a qmldir file for whatever reason, we can still
check for further matching qmldir files in other places. We might, for
example determine that we need to load a plugin, but we have been given
a qmldir file in the resource file system. In that case, we want to
check for other instances of the same module in the host file system.
