arm: [MVE intrinsics] add viddup shape

This patch adds the viddup shape description for vidup and vddup.

This requires the addition of report_not_one_of and
function_checker::require_immediate_one_of to
gcc/config/arm/arm-mve-builtins.cc (they are copies of the aarch64 SVE
counterpart).

This patch also introduces MODE_wb.
