Unity: Universal RP

As Designed

2023.1.X

2022.3.X

BlurredLayerTextureScriptableFeature's OnCameraCleanup(CommandBuffer cmd) function sets RTHandles to null without releasing them causing the memory leak

Reproduction steps:
1. Open the attached project "ReproProj"
2. Open the “/Assets/Scenes/Empty.unity” Scene
3. Enter the Play Mode
4. Observe memory usage with Task Manager or another app

Expected result: Memory usage stops increasing when in Play Mode and releases after exiting
Actual result: Memory usage increases when in Play Mode and does not release after exiting the Play Mode

Reproducible with: 2022.3.11f1, 2023.1.17f1, 2023.2.0b13, 2023.2.2f1, 2023.3.a15
