Adds fork-awareness and finalization notifications to transaction pool watchers. (#4740)

Browse Source 
* adds finalization support to sc-transaction-pool using MaintainedTransactionPool for finalization events

* adds TransactionStatus::Retracted, notify watchers of retracted blocks, finalized now finalizes, transactions for current finalized -> last finalized block

* adds last_finalized to ChainApi, use generic BlockT for ChainEvent

* fix tests

* Apply suggestions from code review

Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com>

* tests

* fix tests, docs, lazily dedupe pruned hashes

* fix tests, Cargo.lock

* Apply suggestions from code review

Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com>

* remove tree_route, last_finalized from ChainApi, add block hash to Finalization and Retracted events

* prune finality watchers

* fix tests

* remove HeaderBackend bound from FullChainApi

* code style nits, terminate stream in finality_timeout
