zink: tighten up export paths that require true dmabuf support

The users of exportable might have different expectations for what can
be exported, and some are more tight. So we need a new exportable_dmabuf
flag to track where dmabuf is actually needed.

If the underlying driver does not advertise dmabuf extension, requesting
dmabuf export violates the spec VU:

> VUID-VkMemoryGetFdInfoKHR-handleType-00671
>
> handleType must have been included in
> VkExportMemoryAllocateInfo::handleTypes when memory was created
