Bug 1677893 - CONFIG["CXX_TYPE"] is not a thing r=firefox-build-system-reviewers,andi,mhentges

Due to lack of `CXX_TYPE`, clang-cl builds were accidentally taking the `else` branch where the `-O0` was ignored/unrecognized. This went unnoticed for a long time until it busted the landing of bug 1677726.

While here, fix the intent of SmokeDMD: `-Og-` is a silent no-op in clang-cl, so it's not actually disabling anything.
