WIP: Replace builtin.pbtxt with one from bazel info starlark-environments-proto

[hauserx]

Follows up WIP change in bazel that adds new bazel info command: bazelbuild/bazel#24817

Some advantages:

• Global symbols are file type specific, suggesting symbols and lint are more accurate.
  • Supporting .bzl, MODULE.bazel, WORKSPACE, REPO.bazel, VENDOR.bazel
• Multiple symbols have additional documentation now, including multiple rules as well as some module-like symbols, like attr
• No special handing for missing globals, those symbols are properly reported by bazel info command
