build: remove deps on legacy nodejs rules rollup_bundle internals

The legacy nodejs rules rollup_bundle is now deprecated and will be removed in the nodejs rules 1.0 release due in mid-November. This PR brings in the rules_nodejs internal API deps that ng_rollup_bundle, ng_package and ls_rollup_bundle depend on into this repo to break the dependency. In the future these rules should switch to use the new rollup_bundle via a macro as done in #33329 but this is not possible right now due to the complication of having esm5 re-rooted ts_library dependencies.
