Fully support all 16-bit packed texture formats

Vulkan lists the following formats as 16-bit packed formats:
 * VK_FORMAT_R4G4B4A4_UNORM_PACK16
 * VK_FORMAT_B4G4R4A4_UNORM_PACK16
 * VK_FORMAT_R5G6B5_UNORM_PACK16
 * VK_FORMAT_B5G6R5_UNORM_PACK16
 * VK_FORMAT_R5G5B5A1_UNORM_PACK16
 * VK_FORMAT_B5G5R5A1_UNORM_PACK16
 * VK_FORMAT_A1R5G5B5_UNORM_PACK16

We already support VK_FORMAT_A1R5G5B5_UNORM_PACK16, so we can use that
as a crossreference to see which tests we expect to pass.
