Automatic GStreamer pipelines for testing cameras (New)

[tomli380576]

Description

This PR implements multiple GStreamer pipelines that tests if a camera is working properly. Given a source element and a Gst.Caps object, we can

1. Take photos
2. Record videos
3. Show a viewfinder

The test script in provider/base/bin also iterates through all the elements and their caps using the output of Gst.DeviceMonitor.

Resolved issues

This is part of the new camera tests that we plan to implement

Real hardware:

• 22.04 and 24.04 Laptops with USB cameras
• 18.04 and 20.04 Virtual machines with v4l2 pass through
