Timo Kreuzer 2881b77302 [CMLIB] Don't redefine PAGED_CODE() to nothing in cmlib.h except for cmlib_host 
This header is included by ntoskrnl which effectively disabled all PAGED_CODE checks since 2015. Thanks Alex.
Instead define _BLDR_ when building cmlib, which will avoid trying to import KeGetCurrentIrql()
