[zircon][display] Set missing display ops in virtio-gpu.

Currently the virtio-gpu driver fails to start, as it fails to implement
three display operations:

    get_sysmem_connection
    set_buffer_collection_constraints
    get_single_buffer_framebuffer

This patch provides dummy implementations of the three operations,
allowing the virtio-gpu driver to successfully start.

Discovered during development of virtio-gpu intergration tests.

Bugs: MAC-213 #comment Avoid crash on virtio-gpu driver startup.
