For loop cleanup

[evildarkarchon]

• I switched the stdout redirection to traditional python file I/O and the text concatenation to f-strings. Traditional I/O does not have implicit newlines (which I get is a convenience of stdout redirection).
• Use some more of pathlib's features.
• Changed the file-list building from os.listdir/fnmatch to glob. glob does in one step what the os.listdir/fnmatch does in 2.
• Only import ctypes.wintypes on Windows. The only code that uses it only runs on windows, so no need to import a module that's not going to be used if the script is being run on linux.
• Stop the gpu detection for loop when it finds either an amd or nvidia gpu (no need to keep searching for something you already found).
• Modified the CK fixes check so that it doesn't just check for the launcher (which hasn't been bundled since v1.6 because Nexus false flags it as a virus).

This was basically the result of a python coding binge I went on. I like how it came out, but I know it's a huge shake-up.
