env/windows: update paths for Windows C compilers
Update the setup script to pick C compilers that are more contemporary
(moving away from old GCC 5.X compilers). The new compilers were
downloaded from this release:
https://github.com/mstorsjo/llvm-mingw/releases/tag/20220323
specifically these files:
llvm-mingw-20220323-msvcrt-i686.zip
llvm-mingw-20220323-msvcrt-x86_64.zip
llvm-mingw-20220323-ucrt-aarch64.zip
To save space on the builders, I unpacked each of these zip files,
removed extra crud, and then re-packed in the form that the buildlet
expects. Specifically, the zip files contain cross-compilers for other
architectures, which we don't really need in our use case.
Updates golang/go#35006.
Details on pruning below.
