Switch to per-shader YAML files (#2459)

Summary:
Pull Request resolved: #2459

## Context

Instead of having an `all_shaders.yaml` file that defines variants for all shaders, switch to having a YAML file for each shader template. This serves two purposes:

1. Makes it easy to find the variants that will be generated for each shader template
2. Reduces the number of potential conflicts of multiple developers adding individual operators.
