Fix gfx::QuadF::IntersectsRect false positives

A rectangle can be fully outside the quad without one of the quad's
edges being a separating axis. We need to check for separating axes
among the edges of the rectangle too to be sure. Add a new method
Extents() to gfx::QuadF to get the axis-aligned extents (AABB) of the
quad.

Keep the old IntersectsRect() implementation, but rename it to
IntersectsRectPartial(). It can be used (as an optimization) when the
pre-conditions allow.

Also fix FloatRoundedRect::IntersectsQuad to correctly consider similar
cases.
