Require validator overrides for blockheader selection mode transitions
A runtime is thrown at startup if this requirement is not met.
Improve ValidatorContractTest: mine an extra block when ending transitions in blockheader mode, such that the test would fail if there were no validator overrides.
First commit for https://github.com/hyperledger/besu/issues/3038
A future commit will cleanup some associated redundant code.

When producing the next block, the previousBlockHeader.number + 1 needs to be used to query the transition forkSchedule.
This is because the list of validators associated with each forkSchedule may be a different set to the current block.
This commit changes the implementation for getValidatorsAfterBlock to support this and points getValidatorsAtHead at this implementation.
Note getValidatorsForBlock's forkSchedule query is unchanged since we have already mined the block at the point this is called (e.g. for RPCs qbft_getValidatorsBy...).
For TransactionValidatorProvider, we need to use the next block's contract address but still use the previous block's validators in the contract call itself.
Querying validators using afterBlock vs forBlock may yield different (blockNumber -> validatorAddresses) combinations when transitioning into CONTRACT mode.
There we also split TransactionValidatorProvider validatorCache into two caches.
Add special case to ForkingValidatorProvider (BlockValidatorProvider.hasValidatorOverridesForBlockNumber) to support transitioning to blockheader mode with some validator overrides. This might be needed if the current validator set loses quorum and we
are no longer able to vote new ones in.
New integration test cases for validatorselectionmode transitions:
- contract -> contract
- contract1 -> blockheader -> contract2
- contract1 -> blockheader with overridden validators -> contract2

Create readOnlyValidatorProvider in QbftBesuControllerBuilder and pass into QbftJsonRpcMethods constructor (better than using protocolContext as is only used once when creating the RPCs
This requires storing transactionValidatorProvider in a field and relying on its earlier creation during createConsensusContext()
Fixes#2795

During the transition from contract mode to block header mode, when creating the extra data for a new block, we need to look ahead to the next block's voteProvider to obtain the nonEmpty one associated with the BlockValidatorProvider.
This only applies to ForkingValidatorProvider which is currently only used for QBFT. However, we don't want QBFT to know it's using a ForkingValidatorProvider. Therefore we need to implement getVoteProviderAfterBlock on the ValidatorProvider interface even though it's implementation is equivalent to getVoteProvider.

Broad reaching optimizations to speed up EVM calculations
* Generally speaking, use int and long where it is more appropriate than UInt256 (memory indexes mostly)
* Move the internal stack to Bytes from UInt256
* Re-work the flow of many operations to account for the above

Move EVM to a standalone module
Move the EVM classes to a standalone module. This is mostly moves but
some API re-resign to peel out some features not essential to the EVM,
such as privacy support and ties to the data storage subsystem.

* Create new datatypes module
Create a new `datatypes` module to hold datatypes that are broadly used.
This will aid modularization by making sure the base types in the module
minimize the amount of unrelated support classes needed.
