Subject: IWYU: Add mapping for 'std::remove_reference<Defer &>::type'

IWYU sometimes thinks that `cmCMakeLanguageCommand.cxx` mentions this
type and suggests including `<type_traits>` for it.  The type is only
used internally by standard library functions.  Work around the problem
by mapping the offending name to a file that we always include.
