Consider caching Alias & Command information

On every textDocument/references request and every textDocument/codeLens request, we rely on the pipeline to get the current available.

This is time consuming and bottlenecked by the pipeline thread. As such, we should consider caching this result based on the state of the Integrated Console.

Coming off the the back of #980, one of the patterns I liked was the ability to tell if something was run in the PSIC using PSRL’s ENTER handler and F8’s handler.

Bringing this concept in, we can use it as a “Dirty” check where we cache aliases and command info results, and only refresh the cache when the PSIC is Dirty.

That way, for example, our textDocument/references request and textDocument/codeLens request only rely on the pipeline once the cache is Dirty and an otherwise run unblocked giving us a perf improvement.

Comienza en src/PowerShellEditorServices/Language/LanguageService.cs, alrededor de la búsqueda vinculada de la línea 327, y revisa después el comportamiento de Integrated Console descrito en #980, incluido el manejador de ENTER de PSRL y el manejador de F8. Define cómo se almacenan en caché y se invalidan la información de alias y de comandos cuando PSIC está dirty; se considera terminado cuando las referencias y las solicitudes de codeLens usan la pipeline solo cuando la caché necesita actualizarse.
