* initial impl of engine-api override:
* remove reliance on isMergeEnabled in pre-merge block header validation rules
* create a merge-specific block header validtion stack rather than leveraging mainnet
* re-add --engine-api-enabled cli param
* make engine api usable without a merge config.
leaves the door open to supporting the engine api with other MiningCoordinators, but disables all but engine_exchangeTransitionConfiguration in the absence of mergeCoordinator

* removed check from fcU if new blocks are descendants of the previous finalized block
* backwards sync: remove check that block must be a descendant of finalized

* Backward Sync is now remembering recent finalized blocks.
When syncing using BWS we now consider finalized blocks reported by consensus layer.
When no finalized block is specified, nothing strange will go on. When Finalized block is specified
But Besu is not aware of any finalized block yet, we will sync as usual until the finalized block is about to get imported.
A new invariant is introduced when importing blocks using BWS.
All imported blocks has to descent from latest finalized block or a TTD block if we did not finalize yet.
* Importing a finalized block updates the information in Besu Mutable Blockchain.
* It is no longer possible to import blocks into the blockchain below a previously finalized block when using BWS
* When a new finalized block gets announced while BWS is in progress and Besu already has it imported, the Mutable Blockchain gets updated, and the chain gets checked for possible pruning
* When trying to import blocks of equal height as newly announced finalized block, then only the new announced finalized block will be possible to import using BWS
* When importing a new block using BWS after finalized, we can now guarantee that the block descends from latest finalized block

Change the unit test execution to use the Junit5 JUnitPlatform. This
allows for a mix of junit 4 and junit 5 tests and for a gradual
migration to junit 5 instead of a big bang. One class depended on
junit 4 exceptions and was updated. Two tests depending on
native libraries fail gracefully on mac (and only mac).
