[Build] No bind for upb (#36349)

To simplify the build process, let's remove unnecessary Bazel bindings. These bindings were originally used to manage differences between OSS and our internal build environment. However, bindings are now deprecated and introduce unnecessary complexity. Removing them will make the build process more straightforward and easier to maintain.

Closes #36349
