[7.2.0] Cherry-picks for starlarkifying all repo rules (#22203)

RELNOTES: Added a new flag `--incompatible_disable_native_repo_rules` to
disable native repo rule usage in WORKSPACE. All native repo rules now
have a Starlark counterpart that can be used in both WORKSPACE and
Bzlmod; see #22080 for more details.
