core/vm, tests: refactored EVM run loop and gas counting

Previously we had a large "requirement" check loop which switched around
every opcode and calculated the gas, checked stack, and resized the memory
when needed.

This has been refactored in to the EVM operation table witch acts as
a large jump table for the EVM containing functions for stack
and gas requirement and execution.

In addition the EVM can now also be used unmetered by setting the
`DisableGasMetering` flag on the EVM config. This will cause the EVM to
run unmetered without gas.

Preliminary benchmarks have given the following results:

**Old vs new (metered):**

benchmark                         old ns/op     new ns/op     delta
BenchmarkVmFibonacci16Tests-4     37668307      21323060      -43.39%

**Old vs new (unmetered):**
