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.

libgcc/ChangeLog:

	PR target/115360
	* config/arm/cmse_nonsecure_call.S: Add .type and .size directives.

(cherry picked from commit c559353af49fe5743d226ac3112a285b27a50f6a)
