update-deps.py: Allow bazel_dep + archive/git_override

[npaun]

This PR adds a new flag to our existing dependency types for downloading packages:

• github_release
• github_tarball
• git_clone

If use_bazel_dep: true is set, we generate a bazel_dep() + an override directive (e.g. archive_override() or git_override(). Otherwise, we use the existing templates for a WORKSPACE based repo.

Additionally use_module_bazel_from_bcr: some.version.here can be used to automatically download an inject a MODULE.bazel file from BCR if one is available from there, but not in the project itself.

This is basically the last PR in my project of upgrading update-deps.py. There's probably still room for small simplifications / cleanups down the road, but the vast majority of our dependencies are now automated again.
