Private accounts are not able to change the state of public accounts. When transferValue is called in MessageCallProcessor it attempts to get a mutable account. This is only required when a transfer of value is happening. If a transfer of value from a private contract to a public contract is attempted an error will be thrown.

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.

Rollback TransactionGasCalculator
Rollback the transactionGasCalculator changes. This was done in
preparation for the EVM modularization. Instead, de-structure the data
needed to calculate the gas instead of passing in the whole transaction.

* 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.

* Add Address, Hash, and Wei to datatypes
Move the Address, Hash, and Wei to datatypes in as they are needed for
EVM modularization.

* allow onchain privacy group proxy calls under group lock
Prior to this commit, the only allowed transactions in locked onchain
privacy groups were those making the addParticipants call to *any*
contract--not just the proxy. This commit ensures that:
- while locked, only the group management proxy can be called
- while locked, all functions of the management proxy can be called
Corollary, this commit allows unlocking a group using unlock instead
of implicitely unlocking it via addParticipants. This fixes#2693.

In preparation for the EVM library pull out the transaction related gas
calculations and move them into their own `TransactionGasCalculator.`
This has 4 calls right now, none of which occur inside the EVM:
* Intrinsic gas cost
* Code Deposit gas cost
* Max refund quotient
* Max Privacy Marker Transaction intrinsic gas cost.

EIP-1702 account versioning was a candidate for the Istanbul hard fork
but was removed prior to the first testnet. Other versioning techniques
have greater core dev mind share and one preparatory step landed in
London, EIP-3541, making EIP-1702 very unlikely to make it to Mainnet.

* Fixed bug where the EthGetTransactionCount would return a lower value for pending than latest when there are old transactions in the transaction pool.
Wrote a failing test to show the expected behaviour and ensured that the max of latest and pending is used.

* Less Spotless Gradle Warnings
Spotless and Gradle 7.x does not play nicely with using a fileTree as a
target and should be using plain strings. This should get rid of the
`Execution optimizations have been disabled`... warnings.
* Move Generated Reference Tests into the `build` dir
Generated reference test are currently generated into `src`, which is in
violation of the standard maven layouts. They should be in the `build`
directory as they are artifacts not maintained in source control.
