Update many dependencies

Go dependencies are updated and moved to a root go.mod file
Bazel dependencies have been migrated to a MODULE.bazel file
Goma has been patched to use the same version of protobuf and abseil
that bazel is building with
golint has been replaced by nogo as golint becomes very slow when a
go.mod file is present
The //external folder has been deleted and all contents is moved to
//third_party/...

Test: Presubmits pass, local testing has been done on linux, mac and
windows
Bug: b/303263153
