IntersectionBoard optimizations

* SSE doesn't have unsigned max and compare instructions. Convert to signed integers. * Don't twiddle bits when widening the intersection masks from 8 to 16 bits. Instead, we can just zip the vector of 8-bit elements with itself. * Improved use of builtin intrinsics in rive::simd. Diffs= b098ad23a IntersectionBoard optimizations (#6486)
