[move-prover][cli] Add benchmark functionality

This adds a new option `aptos move prove --benchmark` which lets verification run in the benchmark framework of the `move-prover/lab` tool. This tool verifies function by function and detects timeouts as well as measure verification time.

The result of the benchmark will be stored in `<move-package>/prover_benchmark.fun_data`. A graphic representation will be stored as well in `prover_benchmark.svg`.

The PR fixes also some other things on the way which came apparent when working on it, namely trying to identify the reasons for #15605:

- Adds new debug print for which verification targets are generated. This is reachable via `move prove -v debug`
- Reduces unnecessary verification of symmetric type instantiations `f<#1, #2>` and `f<#2, #1>`
- Adds an option `--skip-instance-check` to completely turn off verification of type instantiations.
- Removed legacy verification_analysis_v2 and global_invariant_instrumentation_v2. These are dead code since long  and confusing when trying to understand what functions are verified
