MVKPixelFormats enables atomic capabilities only when applicable.

Start with no Vulkan atomic feature bits and add VK_FORMAT_FEATURE_STORAGE_IMAGE_ATOMIC_BIT
and VK_FORMAT_FEATURE_STORAGE_TEXEL_BUFFER_ATOMIC_BIT if Metal format supports it.
Currently only applies to formats MTLPixelFormatR32Uint and MTLPixelFormatR32Sint.
Enable for linear tiling only. Previously optimal was enabled too.
Add kMVKMTLFmtCapsAtomic.
Add kMVKVkFormatFeatureFlagsTexAtomic.
Add kMVKVkFormatFeatureFlagsBufAtomic.
