Jordan Hrycaj b7bf84a71f 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.

Jordan Hrycaj b4f8450968 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
