[HDRP] Deleting a decal material that is currently in use crashes the render loop
Version tested: 2022.2.a16 (17114ee23d5f) + HDRP from Packman
Steps to reproduce:
1) Simply create an empty HDRP project
2) Create a decal material, a decal project and assign mew material to it
3) Delete the decal
4) Observe that projector is showing Material missing and render loop breaks
Note: Same happens with decal SG
Proposed result: projector fallbacks to default decal mat to avoid this.

MissingReferenceException: The object of type 'Material' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
