Automated cherry pick of #61575: Remove all upstream BUILD, BUILD.bazel, and WORKSPACE #57600: Vendor gazelle #62499: Update kazel to include openapi tag detection fix

Cherry pick of #61575 #57600 #62499 on release-1.10.

#61575: Remove all upstream BUILD, BUILD.bazel, and WORKSPACE
#57600: Vendor gazelle
#62499: Update kazel to include openapi tag detection fix

This is an alternative to #64928, and would fix #64925.

We can't just cherry-pick #57600, since there was a prerequisite PR and a fixup PR afterwards.
