Add port of AMD's Robust Contrast Adaptive Sharpening (#7422)

Browse Source 
# Objective

TAA, FXAA, and some other post processing effects can cause the image to
become blurry. Sharpening helps to counteract that.

## Solution

~~This is a port of AMD's Contrast Adaptive Sharpening (I ported it from
the
[SweetFX](https://github.com/CeeJayDK/SweetFX/blob/master/Shaders/CAS.fx)
version, which is still MIT licensed). CAS is a good sharpening
algorithm that is better at avoiding the full screen oversharpening
artifacts that simpler algorithms tend to create.~~

This is a port of AMD's Robust Contrast Adaptive Sharpening (RCAS) which
they developed for FSR 1 ([and continue to use in FSR
2](149cf26e12/src/ffx-fsr2-api/shaders/ffx_fsr1.h (L599))).
RCAS is a good sharpening algorithm that is better at avoiding the full
screen oversharpening artifacts that simpler algorithms tend to create.

---

## Future Work

- Consider porting this to a compute shader for potentially better
performance. (In my testing it is currently ridiculously cheap (0.01ms
in Bistro at 1440p where I'm GPU bound), so this wasn't a priority,
especially since it would increase complexity due to still needing the
non-compute version for webgl2 support).

---

## Changelog

- Added Contrast Adaptive Sharpening.

// RCAS is based on the following logic.
// RCAS uses a 5 tap filter in a cross pattern (same as CAS),
// W b
// W 1 W for taps d e f
// W h
// Where 'W' is the negative lobe weight.
// output = (W*(b+d+f+h)+e)/(4*W+1)
// RCAS solves for 'W' by seeing where the signal might clip out of the {0 to 1} input range,
// 0 == (W*(b+d+f+h)+e)/(4*W+1) -> W = -e/(b+d+f+h)
// 1 == (W*(b+d+f+h)+e)/(4*W+1) -> W = (1-e)/(b+d+f+h-4)
// Then chooses the 'W' which results in no clipping, limits 'W', and multiplies by the 'sharp' amount.
// This solution above has issues with MSAA input as the steps along the gradient cause edge detection issues.
// So RCAS uses 4x the maximum and 4x the minimum (depending on equation)in place of the individual taps.
// As well as switching from 'e' to either the minimum or maximum (depending on side), to help in energy conservation.
// This stabilizes RCAS.
// RCAS does a simple highpass which is normalized against the local contrast then shaped,
// 0.25
// 0.25 -1 0.25
// 0.25
// This is used as a noise detection filter, to reduce the effect of RCAS on grain, and focus on real edges.
// The CAS node runs after tonemapping, so the input will be in the range of 0 to 1.
