Support images with linear tiling for transfers

The Vulkan 1.1 spec on vkCreateImage states that "Creation of images
with tiling VK_IMAGE_TILING_LINEAR may not be supported unless other
parameters meet all of the constraints:
* imageType is VK_IMAGE_TYPE_2D
* format is not a depth/stencil format
* mipLevels is 1
* arrayLayers is 1
* samples is VK_SAMPLE_COUNT_1_BIT
* usage only includes VK_IMAGE_USAGE_TRANSFER_SRC_BIT and/or
  VK_IMAGE_USAGE_TRANSFER_DST_BIT"

Also restrict YCbCr image creation in accordance with:

"Creation of images with a format requiring Y’CBCR conversion may not be
supported unless other parameters meet all of the constraints:
* imageType is VK_IMAGE_TYPE_2D
* mipLevels is 1
* arrayLayers is 1
* samples is VK_SAMPLE_COUNT_1_BIT"
