The fix for https://github.com/apple/swift/pull/72632 was not sufficient because when modules are built from textual interface that happens in a sub-invocation which does not have typecheck-from-interface or compile-from-interface requested action. Instead of checking a requested action, set a language option to control whether non-production experimental features are allowed. Resolves rdar://125561443
