[SPIRV][DirectX] Add `Texture*Array` type support

[inbelic]

Required for testing of all Texture1DArray, Texture2DArray, TextureCubeArray, etc, array types and to ensure correct array texture sampling and indexing.

Current Status: Currently the values for DepthOrArraySize/arrayLayers are hard-coded to 1 and the resource kinds are not yet defined for either target.

The first step will be to refine the following acceptance criteria for refinement/estimation.

AC:

• Allow YAML test configuration to specify array resources (e.g. an ArraySlices count and define the various array types)
• DX: Set DepthOrArraySize from ArraySlices and use TEXTURE2DARRAY/TEXTURE1DARRAY/TEXTURECUBEARRAY SRV/UAV dimensions
• VK: Set arrayLayers from ArraySlices and use VK_IMAGE_VIEW_TYPE_*_ARRAY types + VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT for cube arrays
• DX/VK: Update texture upload/readback to iterate over array slices with correct subresource indexing
• Add independent testing of functionality
