provide identical copy of vm folder => vm2, activated by make flag ENABLE_VM2=1 why: vm2 enabled by ENABLE_VM2=1 behaves as vm without ENABLE_EVMC=1 until it doesn't in some future fatch set. this leaves some wiggle room to work on a vm copy without degrading the original implementation. details: + additional make flag ENABLE_VM2=1 (or ENABLE_VM2=0 to explicitely disable) + when both flags ENABLE_EVMC=1 and ENABLE_VM2=1 are present, the former flag ENABLE_EVMC=1 takes precedence, this is implemented at the NIM compiler level for -d:evmc_enabled and -d:vm2_enabled

move stateDB from VMState to chainDB previously, every time the VMState was created, it will also create new stateDB, and this action will nullify the advantages of cached accounts. the new changes will conserve the accounts cache if the executed blocks are contiguous. if not the stateDB need to be reinited. this changes also allow rpcCallEvm and rpcEstimateGas executed properly using current stateDB instead of creating new one each time they are called.

EVM: Apply EIP-6 in the code (affects both vm and vm2) The rationale in EIP-6[1] for changing names to `selfDestruct` applies to code as much as it does to specs. Also, Ethereum uses the new names consistently, so it's useful for our code to match the terms used in later EIP specs and testsuite entries. This change is straightforward, and is a prerequisite for patches to come that do things with the `selfDestruct` fields.
