added D32_S8 format (#2885)

* added D32_S8 format

* fixed isTypelessDepthFormat format for DXGI_FORMAT_R32G8X24_TYPELESS

* added R32_FLOAT_X32_TYPELESS format to allow (depth component only) shader resource views for the D32_FLOAT_S8_UINT format.
- unsure about the changed in the vk-util.cpp: No matching VK_Format?
