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.

* config/arm/cmse_nonsecure_call.S: Add .type and .size directives.
