Test multiple rasp during one request

[estringana]

Motivation

During the implementation of RASP TELEMETRY on php team, it was found that the WAF will match only once if rasp data is given as persistent instead of ephemeral.

Here you can see the signature of the ddwaf_run method on the WAF: https://github.com/DataDog/libddwaf/blob/1de83d9ae46cb453240202bb5ee568c4cd0d35b4/src/interface.cpp#L190

This test aims to ensure that all languages are passing rasp data as ephemeral, otherwise on scenarios like this, the waf will only report one match instead of three.

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes (if something not related to your task is failing, you can ignore it)
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner. We're working on refining the codeowners file quickly.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed, you can merge it!
