Transaction level execution

[pdrobnjak]

Describe your changes and provide context

Refactor of the evmc and geth VM.

First an improvement on the abstraction - we're working on transaction executor level, not on the VM level.

Second, we can leverage the same executor implementation to cover both evmone and geth cases.

Removing everything that's redundant since second point holds true.

Testing performed to validate your change
