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 [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:

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.
