feat: consolidated harness

[sinui0]

This PR consolidates our integration tests and benchmarks into a single harness.

Opened as a draft as I still need to re-add memory profiling and bench plots. Also needs a little work on configuration

Highlights

• Shared code for tests and benches.
• Supports native and browser. This means that tests only have to be written once and they will be run in both environments.
• Simplify writing and maintaining tests using providers for dependency injection. We no longer have to duplicate setup and tear down of IO everywhere.
• No more sudo and virtual network interfaces. The harness uses our network utilities in tlsn-utils to configure bandwidth and latency for benchmarks. This lets us get rid of the docker dependency as well.
• Should reduce build/CI times.
• Clap CLI for configuration
