RGFW does not compile under Windows with Clang due to RegGetValueW

[mpalomas]

RGFW does not compile under Windows with Clang 21 due to your usage of RegGetValueW, which, as stated in the official doc here, in the Remarks section, requires _WIN32_WINNT to be set to 0x0600 (Windows Vista I think?).

Maybe you should guard it with #if(_WIN32_WINNT >= 0x0600) like you do in other places?

This seems to be specific to Clang btw. When using MSVC, it seems the _WIN32_WINNT is automatically set to a recent version, not sure, but I did not set if myself and it compiles properly. But using Clang, it fails compiling on RegGetValueW.

This seems like a clang issue considering _WIN32_WINNT ought to be set to the correct value by default. Although it is probably still worth having a check.

But clearly even if there was a guard there would be a bug because of clang not defining _WIN32_WINNT correctly.
