Always parse macro expansions, regardless of language mode, and eliminate the fallback path for very, very, very old object literals like `#Color`. Instead, check for the feature flag for macro declaration and at macro expansion time, since this is a semantic restriction. While here, refactor things so the vast majority of the macro-handling logic still applies even if the Swift Swift parser is disabled. Only attempts to expand the macro will fail. This allows us to enable the macro-diagnostics test everywhere.
