Tentative fix for some of the issues with long paths on windows (in particular with shader cache).
Fixes: #73583
Should fix most of the cases for this: #52799
Note that dir_access already uses the \?\ format for long paths.
My understanding from the microsoft docs is that unicode version of the file functions all support this format.
However, I haven't tested it on older windows versions and there might be some good reasons to not do this
