Make USE_DRAW_PROCEDURAL variation only for vertex programs in UberPost shader

com.unity.render-pipelines.universal/CHANGELOG.md

@@ -25,6 +25,7 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
 - Multiply blend now keeps DstAlpha as it's RGB only.
 - Particle AlphaModulate() renamed to AlphaModulateAndPremultiply() as it does both. Moved separate AlphaModulate() and AlphaPremultiply() to URP shader library. Fix double alpha multiply for ParticleLit.
 - Improved blending modes trigger a material update which tries to keep the existing look intact. This is not always possible and manual blend mode changes might be required.
+- Changed "_USE_DRAW_PROCEDURAL" to be used only in vertex shader in Post Processing related shaders as they are not needed for fragment shaders. In result we now generate less shader variants.
 
 ### Fixed
 - Fixed incorrect premultiply blend mode. case 1260085, case 1357703, [case 1347301](https://issuetracker.unity3d.com/product/unity/issues/guid/1347301/)
