MSVC: Enable control flow guard for release builds
This makes the applications and libraries more safe
and won't cause any binary incompatibility.
It's not supported for MSVC 2015, but since we only
support MSVC 2019 or later in Qt6, it's safe to use
this parameter.
The "-guard:cf" parameter is supported by clang-cl
and intel-cl as well, MinGW doesn't support it.
