    [SDK:ASM][NDK] Improve and synchronize the definition of the SYNCH_LEVEL symbol
(#3943)
    
    In particular, for a given platform (x86, AMD64...) its definition
    depends for uniprocessor vs. multiprocessor NT kernel/HAL (controlled
    by the CONFIG_SMP define).
    
    Regarding the ASM-generated headers (from asm/ksx.template.h), since
    they are generated once for a given platform, and since UP/MP NT builds
    are generated at the same time, these headers need to contain both
    SYNCH_LEVEL definitions controlled by CONFIG_SMP, instead of a fixed
    value. Therefore we need to employ the geninc RAW(...) construct.
    
    [NDK:X86] Add missing x86 CLOCK1_LEVEL and POWER_LEVEL definitions.
