Set _WIN32_IE to 0x500 everywhere and remove where it's not needed.
As we gracefully check if the function is present or not, it's OK to set
this define without having IE 5.0 installed on target
Adds support for a self-contained portable mode in which the
executable's directory is used for application files instead
of directories in the user's profile.
Portable mode is activated by placing a scummvm.ini file in
the executable's directory. The directory must be outside of
the system's Program Files directory to comply with UAC.
Example:
../scummvm/backends/platform/sdl/win32/win32_wrapper.cpp:39:52: warning: cast between incompatible function types from 'FARPROC' {aka 'long long int (*)()'} to 'VerSetConditionMaskFunction' {aka 'long long unsigned int (*)(long long unsigned int, long unsigned int, unsigned char)'} [-Wcast-function-type]
39 | VerSetConditionMaskFunction verSetConditionMask = (VerSetConditionMaskFunction)GetProcAddress(GetModuleHandle(TEXT("kernel32.dll")), "VerSetConditionMask");

There's no point in testing for Windows 10 since the comparison is already "greater than or equals", and it identifies itself as 6.2 for backwards compatibility. Likely it was failing before because the return type was wrong.
Version checks are unreliable anyways, should use feature checks, but "if it ain't broke don't fix it".
