I'm seeing some path length issues when building tokenizers in-place. I'm going to see if I can set up a symlink in the windows setup CI script.

[GregoryComer]

Rebasing to test with #13923 to be safe, but will land today if everything looks good.

Removing 1.0 milestone from this PR in favor of using the pip package, when available. I'd need to make some more aggressive infra changes to the wheel build to make this work when building from source.
