fix: async loading of solid examples in the registry

[wodeni]

Description

Resolves #1483.

Follows up on #1391 to re-introduce solid examples to the registry by fixing the generated imports.

Implementation strategy and design decisions

The old implementation imports solid examples no matter if the example is used. This PR wraps it around an async function to make sure it's only imported when f is invoked.

📊 Performance

Key

Note that each bar component rounds up to the nearest 100ms, so each full bar is an overestimate by up to 400ms.

If a row has only one bar instead of four, that means it's not a trio and the bar just shows the total time spent for that example, again rounded up to the nearest 100ms.
