spirv-reader: ImageQuerySize can be on readonly image

Browse Source 
Fix how handle usage is collected.  OpImageQuerySize
is usable for *any* image that is either MS=1 or Sampled=0 or 2.
(Sampled=0 is not allowed by Vulkan).
So it's usable by storage images or multisampled image.

OpImageQuerySizeLod is usable by Sampled=1 MS=0 images, ie. sampled
images.
