When alpha clip threshold is set to 0, then alpha clip is disabled to avoid degenerate cases. In such cases you should rely on alpha transparency only.

How to reproduce:
1. Open the attached project "Bugreport.zip"
2. Select the "Quad" GameObject in the Hierarchy window
3. Change "Alpha Clip Threshold" to 0 in the Inspector window

Expected results: Alpha channel is enabled
Actual results: Alpha channel is disabled

Reproducible with: 2022.3.12f1, 2022.3.15f1, 2023.2.3f1, 2023.3.0a17
