rule overlap between MobSF and mobsfscan

Purpose

Providing proof and data to support deprecating MobSF in a correct way.

1. MobSF rules are regex without tests --- meaning we need to translate every rule into semgrep, and add a lot of test from scratch.
2. mobsfscan rules are partly regex and partly semgrep, both with tests --- meaning we need to translate only some regex, and no need to craft tests.
3. If mobsfscan rules covers most of MobSF rules, it's reasonable to apply 2.
