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

added compiler flag sentinels to vm2 headers why: making sure that deep links into vm2 sources are configured properly. it is intended that only the vm_*.nim interface headers are allowed to source files in vm2. the sentinels just protect from coding errors.
