Relax constraints on src coeff in GrDrawState::willBlendWithDst.

Allow the srcCoeff to be anything as long as it does not reference the dst. Previous version
required srcCoeff to be one.

These tests stress pathops by describing the union of circle-like paths that have tiny line segments embedded and double back to create near-coincident conditions.

The fixes include
- detect when finding the active top loops between two possible answers
- preflight chasing winding to ensure answer is consistent
- binary search more often when quadratic intersection fails
- add more failure paths when an intersect is missed

While this fixes the chrome bug, reenabling path ops in svg should be deferred until additional fixes are landed.
