Only production compilers should apply the per-SDK restriction on loading swiftmodules. Use the "is the compiler tagged" information over a release build to align with the other main swiftmodule loading restriction accepting only swiftmodules built by the same tag. Also use an env var SWIFT_DEBUG_FORCE_SWIFTMODULE_PER_SDK to enable testing this feature in any compilers.
