VFX is not being compiled when unticking Support VFX Graph setting when both URP and HDRP are used as active targets

Steps to reproduce:

1. Open the attached package
2. Open VFX
3. Open SG > Graph Inspector, untick Support VFX Graph box in HDRP active target
4. Save SG

Actual results: Observe that VFX is no longer rendered and errors are thrown

Expected results: If VFX uses the URP Shader as the active target while URP is not the active pipeline in the project, the VFX should display in magenta and an informative warning should appear.
