[VFX Graph] Lit/Unlit particles are not compiled with new ShaderGraph integration when property contains Mode set to Integer

--

-

How to reproduce:
# Open the attached package
# Open Repro Scene (SG is in HDRP, if you are using URP Support VFX Graph flag gonna be needed)
# Open Unlit_VFX SG
# Select Float property in Blackboard
# in Graph Inspector change Mode from Default to Integer

Expected result: Shader is compiled for particles and errors are thrown

Actual result: Shader is not compiled for particles and errors are thrown
