Rollup merge of #101193 - thomcc:win-stdio-nozero, r=ChrisDenton
Avoid zeroing large stack buffers in stdio on Windows Does what it says on the tin, using `[MaybeUninit<u16>; N]` instead of `[0u16; N]`. These buffers seem to be around 8kb, which is big enough that this is likely to be a very nice perf boost to stdio-heavy windows code. r? ``@ChrisDenton`` *(Note: this PR also has a commit that adds windows to CI, but as it mentions I'll revert that after it comes out green -- I can only do a check build on the machine I'm typing this on)*
