cmd/internal/obj/arm64: improve classification of loads and stores

Currently, pool literals are added when they are not needed, namely
in the case where the offset is a 24 bit unsigned scaled immediate.
By improving the classification of loads and stores, we can avoid
generating unused pool literals. However, more importantly this
provides a basis for further improvement of the load and store
code generation.

Updates #59615
