[roll] Roll fuchsia [sysmem] Add goldfish ImageFormat modifiers.

Goldfish Vulkan ICD could create images of two types of tilings:
- linear tiling, specified by FORMAT_MODIFIER_LINEAR (0)
- host GPU-specific optimal tiling.

Since sysmem treats the format modifier as 0 if no modifier
is set, in order to distinguish formats with different tilings
on goldfish ICD, we need to add a format modifier for optimal-
tiled images, similar to other modifiers like "INTEL_I915_X_TILED".

This changes adds a new format modifier to sysmem/sysmem2:
  const uint64 FORMAT_MODIFIER_GOOGLE_GOLDFISH_OPTIMAL = 0x0900000000000001;
to indicate the image tiling.

It also adds a new ImageFormatSet to "image-format" library to
handle that format modifier. Since optimal-tiled memory doesn't
use any memory on guest system, we just set the image size the
same as linear images for sake of simplicity.

TEST=add test cases to image-format-test
