Adds a stub display that emulates a display without actually displaying contents anywhere. This is needed for transitioning Cuttlefish to always using minigbm as its gralloc implementation. Cuttlefish currently uses a custom gralloc and hwcomposer implementation when running without hardware acceleration. The Cuttlefish team would like to start with removing our custom gralloc implementation and use minigbm. For this, we need to add a virtio 2D backend to crosvm. Our hwcomposer implementation currenlly sends framebuffers from the guest to the host via sockets. The gpu backend still requires a display so we need a stub display to use with the 2D backend for the period of time while we are either still using our hwcomposer implementation or until our hwcomposer implementation is updated to use the virtio backend for display.
