API development sometimes requires a redesign while supporting early adopters. Currently this is done by adding @_spi(name) to the API but that requires adding the attribute in import statements as well, causing manual overhead of adding and then removing when the redesign is done. This PR introduces a special spi group name '_' and allows an implicit spi import of a module containing API attributed with '@_spi(_)' Resolves rdar://109797632
