    xen/nospec: Include <xen/stdbool.h>
    
    After introduction of lock_evaluate_nospec() using bool type, building
    Xen on Arm with UBSAN enabled fails:
    
    In file included from ./include/xen/spinlock.h:4,
                     from common/ubsan/ubsan.c:13:
    ./include/xen/nospec.h:79:22: error: unknown type name â??boolâ??
       79 | static always_inline bool lock_evaluate_nospec(bool condition)
    
    There is no issue on x86, as xen/stdbool.h is included somewhere along
    the asm/nospec.h path, which is not the case for other architectures.
    
    Fixes: 7ef0084418e1 ("x86/spinlock: introduce support for blocking 
speculation into critical regions")
