Add progress bar to starknet foundry

[cptartur]

We already show to progress when compiling using USC thanks to #2403

However, after compiling sierra with scarb, snforge spends some time preparing tests to be run. This includes usc compilation but also additional setup. During this setup, snforge still appears like it if was hanging.

Add progress bar that shows the steps of preparing tests to be run in run_for_package function.

Package used for usc spinner already supports multiple bars/spinners, so this should not be that complicated to resolve: https://docs.rs/indicatif/latest/indicatif/struct.MultiProgress.html
