For #61657, we will need a client-side results provider in charge of returning the applications matching the user's query.

As there is currently no way to access the list of registered apps from a plugin, we should also add an additional API to the application service start contract to return a subset of the registered apps meta (title, icon, url)

As we can't leverage ES to perform the search for us here, we will need to implement our own search algorithm. Using Levenshtein distance or a derivate between the query and the application's title is probably acceptable.
