tx-pool: check transaction readiness before replacing (#10526)

* Update to vanilla tx pool error

* Prevent a non ready tx replacing a ready tx

* Make tests compile

* Test ready tx not replaced by future tx

* Transaction indirection

* Use StateReadiness to calculate Ready in `should_replace`

* Test existing txs from same sender are used to compute Readiness

* private-tx: Wire up ShouldReplace

* Revert "Use StateReadiness to calculate Ready in `should_replace`"

This reverts commit af9e69c8

* Make replace generic so it works with private-tx

* Rename Replace and add missing docs

* ShouldReplace no longer mutable

* tx-pool: update to transaction-pool 2.0 from crates.io

* tx-pool: generic error type alias

* Exit early for first unmatching nonce

* Fix private-tx test, use existing write lock

* Use read lock for pool scoring
