_BlitScaleBias is not set when using a custom shader

How to reproduce:
1. Open the attached “TrueBlitterBug.zip“ project
2. Open the “SampleScene“ Scene
3. Observe the Game view

Expected result: GameObjects are visible
Actual result: The Game view is dark

Reproducible with: 2022.3.10f1
Couldn’t test with: 2021.3.30f1, 2023.1.14f1, 2023.2.0b10, 2023.3.0a6 (“UniversalRenderer is missing RendererFeatures“ error in the Console)

Reproducible on: macOS 13.4.1 Ventura (Intel)
Not reproducible on: No other environment tested

Notes:

• Issue reproducible in Player
• _BlitMipLevel is set and _BlitScaleBias is not set, so UV calculation using _BlitScaleBias cannot be performed correctly
• Setting Shader.SetGlobalVector() values to “"_BlitScaleBias", new Vector4(1f,1f,0f,0f)“ minimally solves the issue
