Systematically handle Windows MAX_PATH issues

I feel like I run into [Windows MAX_PATH](https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd) issues more often in `rules_rust` than I do for other rules. I'm wondering if there's a way to address this in a systematic way using the [process_wrapper](https://github.com/bazelbuild/rules_rust/tree/5225e23c9f545c2e990691afcdb6744927a49eeb/util/process_wrapper) or something. But it'd be nice to not need to worry about this since there's apparently solutions (`\\?\` prefixes) that might be able to help.
