cmake: use numeric comparison for `HAVE_WIN32_WINNT`

Turns out CMake supports numeric comparison with hexadecimal values.
Confirmed in GHA/linux-old with CMake 3.7.2. I could not find
documentation about this, but our CMakeLists.txt already used it before
this patch.

Extend that method to two more comparisons.

Also pad the value in the existing one to 4 digits.

The padding/lowercasing logic when setting `HAVE_WIN32_WINNT` is no
longer required, but keep it anyway for uniform log output.

Follow-up to 2100d9fde267eea68f8097ff0a8ba7b3c9742c7f #12044
Closes #14409
