core/txpool: make transaction validation reusable across packages (pools) (#27429)
* core/txpool: abstraction prep work for secondary pools (blob pool)

* core/txpool: leave subpool concepts to a followup pr

* les: fix tests using hard coded errors

* core/txpool: use bitmaps instead of maps for tx type filtering
