__ftol2 is exported from msvcrt on NT6+, not from ntdll for some reason. So native apps still need to statically link _ftol2 and _ftoul2_legacy, but apps linking to msvcrt only need to statically link _ftoul2_legacy (via msvcrtex), when on NT6+.
- Add some of the missing CMake adjustments to continue the configure and compile process with ARM64 MSVC
- Created quick stubs for the functions in SDK needed to finish the configuration process
- Put in an ARM64 option for spec2def
CORE-17518 CORE-17615
- Make __fto64 function more readable
- Call worker function directly for __rt_sdiv/udiv
- Adapt __rt_sdiv64/udiv64 asm shims accordingly
- Add header files to CMake source list

Addendum to f2bc1f0e, e448094e and 54406bf4.
We previously used 2 different versions: one from wine and one from mingw-w64.
The former was used in msvcrt, the latter was statically compiled into the executable. When using MS libs, there is only one _matherr, which is statically linked into the executable and does nothing (it's not really a function for users to be called).
_setusermatherror should only exist in msvcrt and not statically, which wouldn't work at all.
