## 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 Ran `giga/tests`.
## Describe your changes and provide context - adds giga occ flag to initialize_local_chain ## Testing performed to validate your change - funds account after init local chain successfully

Describe your changes and provide context
Has two big building blocks:
gigasequential andOCCblock processorevmcVMand other miscellaneous changes.
gigasequential andOCCblock processorsAdded
gigasequential andOCCblock processors along with config control flow for deciding whether to use them, block processing code has been mostly c/p'ed from existing block processor with minor changes.Sender recovery is done before transaction processing, in the future when we move to pipelined execution phases we can move to doing sender recovery in parallel for every transaction in block.

Tested locally - these changes should not affect production unless giga executor is enabled via config.
