refactor(benchmarks): linter benchmark re-run parsing and semantic on each iteration

[overlookmotel]

Refactor linter benchmark so it parses and generates Semantic afresh before each measured iteration.

This is more realistic usage - in real world you'd never lint the same file repeatedly - and may make cache utilization in the benchmark more realistic.

It also prepares the way for upcoming changes where ContextSubHost::new will take an owned Semantic instead of Rc<Semantic>.
