  [CIR][AArch64] Add lowering for vaba_* and vabd_* builtins (#183595)

Add CIR lowering for the following AdvSIMD (NEON) intrinsic groups:

* vabd_*  – Absolute difference

https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#absolute-difference

* vaba_*  – Absolute difference and accumulate

https://arm-software.github.io/acle/neon_intrinsics/advsimd.html#absolute-difference-and-accumulate

Tests for these intrinsics were split out from:
  * "test/CodeGen/AArch64/neon-intrinsics.c"

and moved to:
 * "test/CodeGen/AArch64/neon/intrinsics.c".

The following helper hooks were adapted from the ClangIR project:
  * `getNeonType`, `emitNeonCall`, `emitNeonCallToOp`.

Credit to the ClangIR contributors for the original implementation.
