Ken Pruiksma ef5b49fc2b Adjust the sharpness of TAA's Catmull-Rom filter based on local area luminance (#3400) 
* Adjust the sharpness of TAA's Catmull-Rom filter based on local area luminance.
This helps prevent ringing artifacts in high contrast areas. Due to Catmull-Rom's use of negative weights, it's possible to have a very high value neighbor sample with a negative weight completely overwhelm the result leading to a negative output. This change reduces the sharpness of the catmull rom filter in high contrast areas so the negative weights contribute less to the final result.

* PR review feedback fixes - more comments and updated the way the sharpness equation was written for clarity.
