perf(scanning): add scan filter options (#407)

### Description

Working on improving performance of scans that include SCA rules by
allowing the CLI to pre-scan a repo to determine what packages and
ecosystems are in use and providing those as filter options to
dramatically reduce the number of rules returned.

### Testing

Working E2E locally with `semgrep-app` and `semgrep-proprietary`
pointing at this branch
