*Steps to reproduce:*

1. import the procided Package

2. Drag and Drop the VFXG_RandomHLSL.vfx in a scene

3. Open the VFXG_RandomHLSL.vfx

4. Notice that the Graph isn't compiling and spill errors:

*Actual results:* 

Shader error in '[VFXG_RandomHLSL] [Simple Burst] Initialize Particles': 'asuint': no matching 1 parameter intrinsic function; Possible intrinsic functions are: asuint(double, out uint x, out uint y) asuint(float|half|int|uint) at kernel CSMain at VFXG_RandomHLSL.vfx(192) (on d3d11)

Shader error in '[VFXG_RandomHLSL] [Simple Burst] Initialize Particles': undeclared identifier 'systemSeed' at kernel CSMain at VFXG_RandomHLSL.vfx(192) (on d3d11)

Shader error in '[VFXG_RandomHLSL] [Simple Burst] Initialize Particles': undeclared identifier 'VFXFIXED_RAND' at kernel CSMain at VFXG_RandomHLSL.vfx(192) (on d3d11)

*Expected results:* As stated by the doc, user should be able to generate Fixed random value easily thanks to this function:
https://docs.unity3d.com/Packages/com.unity.visualeffectgraph@17.0/manual/Block-CustomHLSL.html

*Reproducible with versions:* 

*Not reproducible with versions:* 

*Can’t test with versions:* 

*Tested on (OS):* 

*Notes:*
* The Documentation also seems a bit imprecise:

|VFXFIXED_RAND|float|Generate a random scalar value for each VFX Graph system.|
This seems wrong. The correct doc could be:
Generate a random scalar value for each VFX Graph system.
