Add ABGR format with 10-bit components packed in 64-bit per pixel. This format can be used to handle VK_FORMAT_R10X6G10X6B10X6A10X6_UNORM_4PACK16 on little-endian architectures.

Ok so 0xff and 0xfb for a true 16bit format have a slight difference, whereas for this truncated format they're both max brightness. So yeah there's a difference and I guess we need to add this.
