...and a bunch of other things as I worked through the rot. Notably:
- Upgrade to bazel 4.0.0

This is required only for the built-in bazel nogo functionality.
Since we roll these targets manually via the wrappers, we don't need
to use go_tool_library. The inconsistent use of these targets leads
to conflicting instantiations of go_default_library and go_tool_library,
which both contain the same output files.
