[profiles] Support GPU feature overrides in DAP

[khewonc]

What does this PR do?

Allows GPU feature to be overridden by DAPs (requires DDAIs)

Motivation

https://datadoghq.atlassian.net/browse/AGENTONB-2322

Additional Notes

Anything else we should know when reviewing?

Minimum Agent Versions

Are there minimum versions of the Datadog Agent and/or Cluster Agent required?

• Agent: vX.Y.Z
• Cluster Agent: vX.Y.Z

Describe your test plan

• Deploy the operator with profiles enabled and DDAI disabled
• With DDAI disabled, try setting GPU feature overrides. It should give a reconciler error (which can be viewed in the DAP status)
• Enable DDAI and ensure a DAP with GPU feature overrides only (no node agent overrides) is valid and that the GPU settings can be overridden

Checklist

• PR has at least one valid label: bug, enhancement, refactoring, documentation, tooling, and/or dependencies
• PR has a milestone or the qa/skip-qa label
