Revert "Add some optimizations to PolyUtils"

This reverts commit 8bb0db3d07450880d346d808018708416c928657.

Reason for revert: Breaking Google3.

Original change's description:
> 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.
