iva kik 687f799b7f kernel/queue: fix queue append/get race 
k_queue_append and k_queue_alloc_append are in a race
    condition.

    Scenario:
    Using either of the above mentioned functions from a
    preemptive context, can lead to the element being
    appended to the queue to be lost. The element loss happens
    when the k_queue_append is interrupted at a critical point,
    when the list only contains one element and k_queue_get is
    called, before the k_queue_append is allowed to complete.

    Fix:
    Move sys_sflist_peek_tail inside queue_insert(). Add additional
    bool paramenter to queue_insert(), to indicate append/prepend
    operation.
    Fixes #29257
