    Windows: Modify signature of buf_CleanAsync and buf_CleanAsyncLocked
    
    The buf_CleanAsync() and buf_CleanAsyncLocked() signature does
    not include a cm_scache_t pointer even though buf_CleanAsyncLocked()
    needs a pointer to the matching cm_scache_t object.  There are
    some calls when the cm_scache_t object is already known.  For those
    cases it is more efficient to avoid the additional lookup especially
    when buf_CleanAsync*() is being called on every buffer associated
    with the cm_scache_t object.
    
    At the same time add a flags field and a constant
    CM_BUF_WRITE_SCP_LOCKED to permit the lock state of the cm_scache_t
    to be passed in.
    
    Finally, fix up the usage in buf_FlushCleanPages() which gains
    the most from these changes.
