[PATCH vkd3d] vkd3d-shader/hlsl: Add support for texture arrays. Replace sampler_dim with resource_dim.

[Francisco Casas]

I realized that the initialization of Texture2DMS, and Texture2DMSArray 
is not correct on this patch.

These textures require a "number of samples" parameter, as in Gio's branch.

Still, the rest of the patch may be worth considering.
