add a github workflow for re-enabling CI (#398)

Summary:
Re-enable CI for gloo.
1. Disable libuv build in CI for windows as there are linker errors. Will resolve this later.
2. Remove tls_tcp_test.cc as this file does not exist anymore.
3. Put back win.cc and win.h files that were erroneously deleted.
