wayland-protocols: upgrade 1.33 -> 1.34

This release comes with three new staging protocols:

 * xdg-toplevel-drag

This protocol enhances regular drag and drop by allowing attaching a
toplevel window to a drag. This can be used to implement e.g. detachable
toolbars and browser tab drag behavior that can be seen in other
platforms.

 * xdg-dialog

This protocol allows setting dialog specific hints on a toplevel, more
specifically marking them as modal.

 * linux-drm-syncobj

This protocol will allow explicit synchronization of buffers using DRM
synchronization objects. While being a protocol that is unlikely to be
widely used directly by applications and toolkits themselves, it is an
important building block for improving Vulkan and OpenGL drivers.

Other than this, the tablet and foreign toplevel list protocols also
received clarifications and fixes.
