Update consensus tests to v11 (erigontech#4724)

* Consensus tests update 11

* Add GrayGlacier fork

* Wire currentRandom from tests into PREVRANDAO

* Serenity engine

* Support insertion of PoS blocks in MockSentry

* Introduce marshallTypedTransactionsAsRlpStrings arg into (*Block) RawBody()

* Revert "Introduce marshallTypedTransactionsAsRlpStrings arg into (*Block) RawBody()"

This reverts commit 903fca5.

* Post-merge fix

* Don't wait for Beacon Chain in tests

* Skip powToPosBlockRejection transition test

* ForkChoice in insertPoSBlocks

* Add withPosDownloader arg to MockWithEverything in order to fix TestPoSDownloader
