ci: try runs-on Dronecode Infra

Use the Dronecode AWS Infrastructure for CI workflow runs. This PR introduces access to a paid Dronecode/PX4 AWS account for workflows. Initially, we are only using it for the new "Build All targets" workflow.

To use the Dronecode Infrastructure, you have to add a similar line (runner types available):

runs-on: [runs-on,runner=8cpu-linux-x64,image=ubuntu22-full-x64,"run-id=${{ github.run_id }}"]

Current Setup

• CPU: 8 cores
• RAM: 32GB
• AWS EC2 Type: m7a.2xlarge
• Max Concurrent Servers: 60

Debug Access

• Any user with Github admin access and a valid SSH key configured in github.com
• Click on the "Set up job" step and access the runner details

Build Time Comparison (additive)

• Dronecode Infra: 2h 18m 42s
• Github Runners: 4h 34m 2s

Cost Considerations

We have provisioned 4k build minutes and expect to not meet the limit any time soon, but we will be heavily monitoring for any abuse of the system.

Note: we are using the runs-on project for our AWS deployments.
