The displacement scaling material node doesn't work correctly with material instances that do not create static permutations, and we can't assume that displacement scaling of the material can be known as final during material translation. As a result, we stop trying to determine if a constant displacement could effectively disable tessellation and instead return to disabling displacement when the displacement pin has not been connected, which can still be used (via Material Attributes) to disable displacement based on static switches.

- UTextureCollection data asset that just holds an array of Texture assets.
- Uses the new RHIResourceCollection RHI resource type which puts all the texture bindless indices into its own buffer.
- Adding TextureCollection material nodes for accessing and sampling from Texture Collections.

Code now checks for this occurrences and reprorts an error message instead of siliently trying to compile the material anyway.
This was causing a crash when two material functions containing the same parameter bound to different values (e.g. different textures) are used in the same material.

- Use material F0=>IOR by default.
- Then use the root node refraction pin input to override IOR for art direction.
- Refraction is now disable using the mode None.
- This data converted according to the graph content. Usingthe Rectraction input is detected by looking at all the node from the mateiral graph. When material attributes are used however, It is however over conservative since it does not check if the node a really plugged in an actual attribute path.
It was needed to deprecated the previouls RefractionMode variable as default value needs to now be RM_None. The new property is RefractionMethod.
The new GetRootNodeOverridesDefaultRefraction function on FMaterial has a default but to have correct refraction it must be implemented when it matters.
Refraction engine test were all green.

* Add a new thickness input on the root node for thin surface
* Add a new thickness input on vertical layer operator, to provide the thickness of the 'layered' material
* Mark Slab thickness input as deprecated, for converting existing asset once this CL is checked in.
