Faster caching glue

[mpkorstanje]

🤔 What's changed?

Work in progress. Parking this in a pull request so I won't forget about it.

Currently the CachingGlue is rather limited in what it can cache. Step definitions are derived from parameter types, and because these can be Disposable, this means that we dispose of the whole cache after each scenario.

But glue can be reused between scenarios if

• The step definitions are non-disposable.
• The step definitions are the same as the previous scenario
• The the language of the scenario is the same.
