CMake: Fix failing 32 bit debug builds on MinGW
When doing a doing a 32 debug build, and trying to compile
one of the qml type registrations files, the following error can
happen
as.exe: quick_qmltyperegistrations.cpp.obj: too many sections (44466)
Fatal error: can't close src/quick/CMakeFiles/Quick.dir/quick_qmltyperegistrations.cpp.obj: File too big
The fix is to compile these specific files with the -Wa,-mbig-obj
compile flag, which uses a munged COFF format that allows more than
32k sections in one file.
Task-number: QTBUG-84886
