[skia_renderer] - Don't explicitly clip scissor for large transforms

This adds a check to CanExplicitlyScissor that confirms that the device
space scissor rect, transformed to the quad's local space, can be
transformed back to device space and equal the same pixel bounds.

Without this check, sufficiently large scales and translates could
cause the local-space coordinates of the scissor rect to be in a float
range that does not have single-pixel precision, meaning it could round
significantly. Clipping the quad's coordinates to those rounded edges
and then transforming to device space can result in coordinates that
fall outside the original device-space scissor rect.

If however, we ensure we can round-trip the scissor coordinates, then
any clipping to the quad's coordinates will also be projected to within
the scissor rect as well.
