  [CIR][AArch64] Upstream addition-across-vector (incl. widening) NEON builtins (#193396)

Related to https://github.com/llvm/llvm-project/issues/185382

CIR lowering for addition-across-vector intrinsics
(https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#addition-across-vector)
and addition-across-vector-widening intrinsics
(https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#addition-across-vector-widening)

Port tests from clang/test/CodeGen/AArch64/neon_intrinsics.c and
clang/test/CodeGen/AArch64/neon-across.c to
clang/test/CodeGen/AArch64/neon/intrinsics.c
