Metal and AMD/Intel/Vulkan don't support depth24 texture formats natively. The backends implemented fallback to use depth32f in stead. Recently we removed all usages of depth24 to use depth32 and the next step is to remove the depth24 format and the workarounds in the backend. Note: The removal of `GPU_DATA_UINT_24_8` isn't part of this PR. Pull Request: https://projects.blender.org/blender/blender/pulls/140659
