```
improve comptime windows GUID.parse performance

I found that after switching from my custom Guid parser to the one in std that it increased zigwin32 build times substantially (from 40 seconds to over 10 minutes).  More information can be found in the benchmark PR I created here: https://github.com/ziglang/gotta-go-fast/pull/21 .  This PR ports my GUID parser to std so all projects can leverage the faster comptime performance.
