fuchsia: Set sysmem constraints only if format/tiling/usage valid on host.

Host Vulkan driver may not support some specific format, tiling and
image usage combinations. Before guest ICD set up sysmem buffer
collection constraints, guest needs to verify the image properties
to ensure that this works on host Vulkan driver, otherwise it may
cause further issues with the ColorBuffer/guest Vulkan image.

TEST=chromium test on FEMU.
