Bazel7 Workspace Support

[bstoll]

This change updates the build process to use newer tooling with Bazel WORKSPACEs.

• In WORKSPACE, prefer to load dependencies closest to the project first.
• Gazelle builds go deps (bazel run //:gazelle_update_repos)
• Gazelle can generate BUILD files (bazel run //:gazelle) for protos & Go.
• Sync up go.mod and WORKSPACE versions
• Start using import_prefixes more consistently. This should make GRPC reflection work a bit better.

This is notably missing bzlmod support. We need to import GNSI, GNMI, and bootz into this repo but none of these use bzlmod yet. I believe the best way is to start at the bottom and migrate them one by one (starting with GNMI) - alternatively, we could patch them up but this is a bit clunky to do.

The GRPC compiler has an arg difference that results in different generated output: GRPC interfaces generally include mustEmbedUnimplementedXYZ, while the @io_bazel_rules_go//proto:go_grpc_v2 does not enforce this. Since we already generate with the mustEmbed, it would seem ideal to keep doing this.
