Use gazelle generated bazel files

Bazel build files are now maintained primarily with `bazel run
gazelle`. This will analyze and merge changes into the build files as
necessitated by certain code changes (e.g. the introduction of new
modules).

In some cases there hints to gazelle in the build files, such as `#
gazelle:erlang...` or `# keep` comments. xref checks on plugins that
depend on the cli are a good example.
