Log:
[CMAKE/MSVC] Enable function level linking and comdat folding independent from build type.
This reduces freeldr size and allows to build with /RTC1 again. Since GCC doesn't
support function level linking, cmlib should be refactored by moving some functions into
different source files to avoid linking unused code into freeldr.
