wayland: Don't delay pending surface resize handling on Vulkan.

Browse Source 
OpenGL apparently needs to not do any drawing between wl_egl_window_resize
and eglSwapBuffers, but Vulkan apps don't use SDL to present, so they
never call into an equivalent of SDL_GL_SwapWindow where our Wayland code
was handling pending resize work.

Fixes Bugzilla #4722.
