Some filters in queries are used more frequently than others, making it tedious to search for them each time.
This patch adds the ability to bookmark filters so they always appear at the top of the "Add filter" dropdown, marked with a ⭐ in their names.

On the query page, a "Bookmarked filters" section is added, containing a select box with the filters available to the user for that query.
When this select box is updated, the bookmarks are saved and the options in the "Add filter" dropdown are updated immediately.

The "Bookmarked filters" section is also added to the "Gantt" and "Calendar" tabs, since they also use filters. Bookmarks in these tabs are shared with the issues query.

Additionally, this patch refactors the selection of the group for a filter from the QueriesHelper#filters_options_for_select method into a separate method. This reduces the complexity of QueriesHelper#filters_options_for_select and makes it easier for plugins to add new groups to query filters.
