Add options to hacky-dev-image-build task to build {process,trace}-agent

[L3n41c]

What does this PR do?

Add --process-agent and --trace-agent options back to the agent.hacky-dev-image-build invoke task to also build the process-agent and trace-agent and copy them in the docker image.

Motivation

These options were removed when we migrated to single binary.
But they weren’t added back when the single binary was reverted.

Describe how to test/QA your changes

Run something like

inv agent.hacky-dev-image-build --base-image gcr.io/datadoghq/agent:7.58.0-rc.4 --target-image europe-west3-docker.pkg.dev/datadog-sandbox/lenaic/agent:latest --push --process-agent --trace-agent

and validate that the agent, process-agent and trace-agent inside the docker image are your custom ones.
