Jason Macnak 327fc2454c virtio-gpu: implement 2D GPU Backend ... ... which does not require virglrenderer (or any renderer). This will allow the Cuttlefish team to use minigbm as its gralloc implementation when both hardware acceleration is available and unavailable. Adds a GPU `Backend` trait with all of the existing methods of the current backend and converts the existing `Backend` into `Virtio3DBackend` which implements the new trait. Adds a `Virtio2DBackend` which creates resources with byte vectors on the host and implements transfers via the old code from gpu_buffer/src/lib.rs. Adds a runtime flag to select between 2D and 3D mode with 3D mode as the default. Moves the process_resource_bridge() function to the `Frontend` and instead expose a export_resource() function on the `Backend` to avoid some code duplication.
