[PATCH 2/2] user32: Add a new __wine_set_desktop callback.

Fri Nov 19 05:23:39 CST 2021
Since fd675485be8686ec5e3b4667d3f3e9739a4a07ce, the graphics driver
initialization sequence changed for the desktop process. The desktop
thread loads the graphics driver directly, and that makes it fill the
user driver callbacks without going through load_driver anymore.
This makes register_builtin_classes to not be called anymore in the
desktop process, and IME window creation to fail when the systray window
is created.
It is noticeable as ImeSetActiveContext and ImmReleaseContext are
printing a FIXME, and possible side effects aren't completely obvious,
but we should probably make sure builtin classes are registered.
This restores a call to register_builtin_classes by redirecting graphics
driver wine_create_desktop callback through user32.
