…ullscreen Master Stack pages.

Added a reference to the custom renderer feature page.
Added a reference to custom-post-processing.md on the customizing-urp.md page.
Implemented the same structure as in the 6000 version.
Copied Fullscreen Master Stack pages, the feature is implemented in 2022.3 and was not documented in URP.
Converted the formatting from the main manual to URP.

-# Custom post-processing
-
-The Universal Render Pipeline (URP) provides a variety of pre-built [post-processing effects](https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@15.0/manual/integration-with-post-processing.html) that you can adjust to create a particular visual effect or style. URP also lets you create custom post-processing effects using the [Full Screen Pass Renderer Feature](../renderer-features/renderer-feature-full-screen-pass.md). For example, you can implement a grayscale effect to indicate when a player has run out of health.
