[graphics] Remove VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT from vkreadback.

The Vulkan docs for VkImageCreateFlagBits at
https://www.khronos.org/registry/vulkan/specs/1.3-extensions/man/html/VkImageCreateFlagBits.html
imply that VK_IMAGE_CREATE_MUTABLE_FORMAT_BIT is only needed to create
a VkImageView with a different format than the image. The vkreadback
test does not have this need.

Bug:
Test: fx test //src/graphics/tests/vkreadback //src/graphics/tests/vkext
