user32: Do not delay-load setupapi.
This fixes a deadlock in the Steel Series Engine installer, between the
"user_section" lock and the loader lock.
Currently user32 takes the "user_section" lock during THREAD_DETACH, i.e. while
the loader lock is held. However, it is also possible for a thread to take the
locks in the reverse order. The observed path is:
- register_builtin()
- LoadCursorA()
- get_display_bpp()
- get_display_dc()
- CreateDCW()
- GetDeviceCaps(DESKTOPHORZRES)
- GetSystemMetrics(SM_CXVIRTUALSCREEN)
- EnumDisplayMonitors()
- update_monitor_cache()
Since we now rely on setupapi for fundamental tasks such as determining screen
size, it doesn't make much sense to delay-load it.
