Update the logic selecting the most restrictive import for a given reference to account for @_exported imports from the local module. We should always prioritize @_exported imports from the local module over more restrictive same file imports. Only if an import from the same file is also public we prefer it as it's more useful for diagnostics and generally recommended to locally declare dependencies. Also update the test that was meant to check this configuration to apply two different variations, one for a module local @_exported and one relying on the underlying clang module. rdar://140924031
