ns_error_domain can now be used to communicate with the ClangImporter when an enum has an associated error domain string. In this case, when we import it as a Swift enum, we can also synthesize a conformance to _BridgedNSError. This allows the creation of something like NS_ERROR_ENUM, in which the developer can declare an enum for the purposes of error handling. Adds Sema and executable tests demonstrating this funcionality. In order for the imported ns_error_domain bridging to work, we have to at some point forcibly pull in a _BridgedNSError conformance, as one will not be pulled in normally. This is a problem, and is explicitly signaled in the provided test case
