remove rules/rules_go

1. Go needed quite a few hacks to be made work with Go. From
   https://github.com/ziglang/zig/pull/15060 less hacks are needed (but
   still not zero, though now documented).
2. This file was never meant to be exposed as part of
   `hermetic_cc_toolchain`. I probably broke someone. Sorry.
