EEVEE: ScreenSpaceReflections: Improve hit quality
This changes the hitBuffer to store `ReflectionDir * HitTime, invPdf`
just as the reference presentation.
This avoids issues when the hit refinement produce a coordinate that
does not land on the correct surface.
We now store the pdf in the same texture and store it inversed so we can
remove some ALU from the resolve shader.
This also rewrite the resolve shader to not be vectorized to improve
readability and scalability.
