fix(ci): adjust xwin timeout and revert xwin jobs being disabled (#8187)

## Summary

Reverts #8181 and #8182.

The fix is in b849f0f, which extends the run timeout to allow xwin to
download the Windows SDK files, which can take 10+ minutes.

Closes https://github.com/rust-cross/cargo-xwin/issues/127

## Test Plan

Existing CI should pass.

## Notes

xwin jobs will take a long time the first time due to cache re-warming.
