[Unity] Character Dissolve Shader

Stylized dissolve/fade-out for Unity URP characters. Turn any character into a clean, punchy dissolve effect, the kind of "tidy hole" disintegration seen in stylish action games. Holes are sampled in screen space, so density naturally scales with camera distance without any extra distance-calculation code.
