Add initial MaxStack calculation

[buyaa-n]

This is initial MaxStack calculation for simple (no branching) instructions, basically UpdateStackSize(OpCode opCode) will be called for each OpCode emit and updates the _currentStack based on its StackBehaviourPush, StackBehaviourPop values.

        private void UpdateStackSize(OpCode opCode)
        {
            _currentStack += GetStackChangeFor(opCode.StackBehaviourPush) + GetStackChangeFor(opCode.StackBehaviourPop);

            if (_currentStack > _maxStackSize)
            {
                _maxStackSize = _currentStack;
            }
        }

This calculation will be updated as needed when branching IL.Emit overloads implemented.

As I cannot use the internal OpCode.StackChange() method created int GetStackChangeFor(StackBehaviour stackBehaviour) method

LGTM pending API approval.

Note there are some unaccounted test failures. Perhaps rebase\merge to latest since I see some recent JIT fixes went in.

Add test for the new API under https://github.com/dotnet/runtime/blob/fe043b489f69a888ad2efd97fbc177c1f25e541d/src/libraries/System.Reflection.Emit/tests/OpCodesTests.cs
