Import gazelle

This patch imports gazelle as a linter. It automatically generates
BUILD file entries for Go code and at the same time keeps BUILD files
formatted.

The `tools/lint:run-ci` target is set up to automatically add new Go
repositories as well.

I added a tool at `//tools/go:mirror_go_repos` that needs to be run
before anyone can merge code that uses third-party Go libraries.
