Support configurable screen sizes

This change enables Cuttlefish to run with a user specified display size on top
of virtio gpu accelerated graphics rendering.

This change makes the width and height an argument/flag and adds the necessary
plumbing to pass this width and height through the gpu backend.

BUG=b:134086390
TEST=built crosvm and booted cuttlefish locally
