Vulkan image formats

4 basic things here: - Set SwiftShader formats to match the equivalent Vulkan format, when available - Removed SwiftShader formats with no exact match in Vulkan formats - Added all currently unavailable Vulkan formats in comments in the list, possibly to be added later, when necessary - Marked all mandatory sampled formats in the list (in comments) Bug b/118429780 Change-Id: I7d7b661e64cb4aee9eb724c64664cee8271cc48c Reviewed-on: https://swiftshader-review.googlesource.com/c/21808Tested-by: 's avatarAlexis Hétu <sugoi@google.com> Reviewed-by: 's avatarNicolas Capens <nicolascapens@google.com>
