Add accelerated cursor composition to ui/cocoa. This does not only improve performance for display devices that exposes the capability to the guest according to dpy_cursor_define_supported(), but fixes the cursor display for devices that unconditionally expects the availability of the capability (e.g., virtio-gpu).
The common pattern to implement accelerated cursor composition is to replace the cursor and warp it so that the replaced cursor is shown at the correct position on the guest display for relative pointer devices. Unfortunately, ui/cocoa cannot do the same because warping the cursor position interfers with the mouse input so it uses CALayer instead; although it is not specialized for cursor composition, it still can compose images with hardware acceleration.
