win,fs: use the new Windows fast stat API (#4327)
Windows added a new API for file information, which doesn't have to
open the file thus greatly improving performance:
https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-getfileinformationbyname
The stat functions are already covered by tests, so no test was added
here. I considered comparing the result of old and new code, but that
would require exposing internal fs functions, and we would be testing
Windows functionality, not libuv.
