    arm: Add .type and .size to __gnu_cmse_nonsecure_call [PR115360]
    
    This patch adds missing assembly directives to the CMSE library wrapper to call
    functions with attribute cmse_nonsecure_call.  Without the .type directive the
    linker will fail to produce the correct veneer if a call to this wrapper
    function is to far from the wrapper itself.  The .size was added for
    completeness, though we don't necessarily have a usecase for it.
