Jon Ross-Perkins 2929254168 Update LLVM version, fix breaks (#4886) 
- The actual reason I started this: minor lowering updates in the golden
LLVM IR
- Process.inc changed enough to need a patch context update.
- https://github.com/llvm/llvm-project/pull/123126 added `proto_library`
uses without a `load`, which is broken in bazel 8
- Just commenting these out because we don't use them. I'll follow up
separately about a possible fix, but continuing to use `WORKSPACE` is a
bigger issue LLVM probably should address.
- Note this update is also triggering removal of `migrate_cpp`, in #4887
