feat: autopilot / driver documentation

[mfw78]

Problem

I'm frustrated at the lack of information around the architecture for the autopilot / driver system and how various components fit together.

Suggested solution

Document the co-location architecture for autopilot / driver / solver.

Alternatives considered

None. We need this 😅

Additional context

The draft templates (not populated) can be found at https://github.com/cowprotocol/docs-v2/tree/main/docs/cow-protocol/tutorials/arbitrate. Feel free to add in any other documents as needed.

Acceptance criteria

• Populate high level @sunce86
  • Architectural mermaid diagram showing relationship of components
  • Descriptions / overviews of autopilot, driver, solver functionality
  • Sequence diagram of the live of an order (from intent to settlement) - auction abstracted away
  • Sequence diagram of a single auction

Using the template suggested by mfw below:

• Populate driver subpage @MartinquaXD
• Populate autopilot subpage @fedgiac
• Populate solver-engine subpage @fleupold

Example for structure of each page:

1. Overview
2. Architecture
3. Methodology (how the component works)
4. Dependencies / interactions
