[gloo] migrate circleci to github 1/N

Summary:
Migrate circleci to github actions.
Circleci has been removed from gloo and the goal here is to revive CI
but use github actions instead.

1. Put back win.cc and win.h that were erroneously deleted.
2. Comment out uv build as this breaks CI because of errors for now. I will
address these in a follow-on diff.
3. Add a build.yaml to do a windows build.

Test Plan:
Test on github.
