Mirrors PR #820 for v0.2.0

Resolves #849

Pull request overview

Mirrors PR #820 onto the v0.2.0 branch by adding port- and controller-level traits (and tps6699x driver implementations) for getting Discovered SVIDs, getting Discover Identity SOP/SOP' responses, and executing Hard Reset. Resolves issue #849.

Changes:

• Adds new SvidDiscovery, HardReset, and DiscoverIdentity traits at both port and controller levels in type-c-interface, plus a new DiscoveredSvids data type in control::svid.
• Implements these traits for the tps6699x driver and for the std example mock controller.
• Wires up heapless as a new dependency of type-c-interface (reflected in workspace Cargo.lock files).
