[AArch64][GlobalISel] Take abs scalar codegen closer to SDAG (#84886)
This patch improves codegen for scalar (<128bits) version
of llvm.abs intrinsic by using the existing non-XOR based lowering.
This takes the generated code closer to SDAG.

codegen with GISel for > 128 bit types is not very good
with these method so not doing so.

++ SVE CodeGen Warnings ++

When the WARN check lines fail in the SVE codegen tests it most likely means you
have introduced a warning due to:
1. Adding an invalid call to VectorType::getNumElements() or EVT::getVectorNumElements()
   when the type is a scalable vector.
2. Relying upon an implicit cast conversion from TypeSize to uint64_t.

For generic code, please modify your code to work with ElementCount and TypeSize directly.
For target-specific code that only deals with fixed-width vectors, use the fixed-size interfaces.
Please refer to the code where those functions live for more details.
