(Reland) Allow ColorBufferVk setup failures

... to match the previous behavior where the Vulkan backing
was deferred until the first actual Vulkan usage of the
ColorBuffer.

Eventually, Gfxstream should fully implement VIRTGPU_GET_CAPS
and properly send support info into the guest gralloc
implementations. Gfxstream VK format support checking should
also potentially be updated to not completely disable a format
if external memory is for that format isn't supported. For
example, VK_FORMAT_R8G8B8_UNORM may not support external memory.
Currently, getImageFormatExternalMemorySupportInfo() seems to
completely disable the format instead of just marking
supportsExternalMemory as false.

Reland note: no changes from previous aosp/2433613
