How to reproduce:
1. Open the attached "case_1388149" project
2. Open the "ReproVFX" VFX Graph
3. Compile the VFX Graph

Expected result: The VFX is successfully compiled
Actual result: Shader errors related with the Shader's "VertexDescriptionFunction" function parameters are thrown in the Console log

Reproducible with: 12.1.2 (2021.2.7f1), 13.0.0 (2022.1.0a11), 13.1.3 (2022.1.0b2)
Couldn't test with: 7.7.1 (2019.4.34f1), 10.8.1 (2020.3.25f1), 12.0.0 (2022.1.0a10) (no "Add Custom Velocity" option in the Graph Settings)

Thrown errors:
Shader error in 'Hidden/VFX/New VFX/System/Output Particle Unlit Quad': 'VertexDescriptionFunction': no matching 1 parameter function at line 4403 (on metal)
Shader error in 'Hidden/VFX/New VFX/System/Output Particle Unlit Quad': 'VertexDescriptionFunction': no matching 1 parameter function at line 5559 (on metal)

Note:
- Compiling the "ReproSG" Shader Graph freezes the Editor
- Reproducible with Metal, DX11 Graphics APIs
- Couldn't test with OpenGL (not compatible with HDRP)
