chore(minor): Reduce dependencies

[hassila]

Description

Reduce dependencies from 12->7;

Removing extras-json and instead use Foundations JSON - we have a Foundation dependency anyway and will hopefully soon move to the new swift-foundation.

Fold in Progress.Swift inline with the project instead of depending on Ordo tagged release version

Fold in BenchmarkClock to remove dependency on Ordo package-datetime

Update NIO locks from upstream

Move Benchmarks to a separate embedded project a la SwiftNIO to allow it to use newer toolchain and remove dependencies

Remove DocC plugin dependency as it is done behind the scenes by SPI anyway

How Has This Been Tested?

Test suite and manually tested on macOS

Minimal checklist:

• I have performed a self-review of my own code
• I have added DocC code-level documentation for any public interfaces exported by the package
• I have added unit and/or integration tests that prove my fix is effective or that my feature works
