arm: [MVE intrinsics] Fix tuples field name (PR 118332)

A recent commit mistakenly changed the field name for tuples from
'val' to '__val', but unlike SVE this name is mandated by ACLE.

The patch simply switches back the name to 'val'.

	PR target/118332

gcc/ChangeLog:

	* config/arm/arm-mve-builtins.cc (wrap_type_in_struct): Use 'val'
	instead of '__val'.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/mve/intrinsics/pr118332.c: New test.
