[Security Solution] Remove deprecated bulk endpoints from v9.0.0 (ela…

…stic#207906)

**Partially addresses: elastic#193184
**Is a follow-up to: elastic#207091

## Summary
This PR removes deprecated bulk action API endpoints from router, making
them unavailable in `v9.0.0` and Serverless.

We've already added an upgrade guide for users of these endpoints in
elastic#207091.

Once our team has more free capacity, we'll open another PR to properly
remove route handlers and associated code (tests, utils, etc.)
