common sw_engine: adds missing composite methods.

Browse source 
Now tvg user could combine Mask Alpha & Mask Method like this:

paint->composite(target, tvg::CompositeMethod::AddMask);

binary size diff: 201307 -> 223399 (+22kb)

@APIs:
- CompositeMethod::AddMask
- CompositeMethod::SubtractMask
- CompositeMethod::IntersectMask
- CompositeMethod::DifferenceMask
