Add some optimizations to PolyUtils

* Switch inset/offset code to use a linked list rather than an array
* Use std::set to store active edge list for IsSimplePolygon rather than array
* Pre-alloc the priority queue for IsSimplePolygon
* When adding radial curves, expand the array all at once rather than pushing
one at a time.
