[test][AArch64][CodeGen] Enhance GOT-related tests (llvm#101968)
- use `-NEXT` for check lines where applicable (as discussed in llvm#96164 (comment)); - move to shorter check prefixes where applicable (e.g. `CHECK` instead of `CHECK-PIC` if it's the only prefix used in the file); - minor formatting.
