The variable was only set by the GNU-like compiler modules, so AUTOMOC never generated a moc_predefs.h for compilers targeting the MSVC ABI and moc parsed headers without the compiler's predefined macros. MSVC dumps its predefined macros with '/PD', which needs the conforming preprocessor. Require VS 2019 16.8, because 16.7 and older ignore the flag with warning D9002 and emit no macros at all. clang-cl takes '-dM' through '-Xclang'. Both also echo the preprocessed source, so feed them an empty translation unit. clang with the GNU driver is excluded from 'Compiler/GNU' as well when it simulates MSVC, so give it the usual '-dM -E' command there. Fixes: #28093
