[Feat] Add more layer selection options to the Query dialog

[wenzeslaus]

Is your feature request related to a problem? Please describe.

When exploring data with several vectors in (Map) Display, I need to often redo my selection of layers being queried. The checked layers are displayed while querying is done on the selected ones. When I need to change style, I loose the selection used for querying. (My use case is exploring the data, so I'm doing trying different things.)

Describe the solution you'd like

I would like to be able to select in the Query dialog what selection from list of layers in Display tab should be applied. So, the Query dialog would have these options:

• Query the selected layers
• Query the checked layers
• Query all layers

These options are exclusive, so they can be represented as a combo/choice box, but it seems to me that it would send a wrong message, something I have to choose as a user and I need to click just to explore. Three toggle buttons would handle that perhaps better: you click when you want to take an action. However, perhaps the gearwheel/sandwich/kebab/⚙️≡⋮ (i.e., more options) button and associated menu with exclusive check boxes would handle this best.

Describe alternatives you've considered

Making the query exactly on what one sees in the Map Display (i.e., checked layers) would make sense. However, picking a different single method seems restrictive and the use case addressed now makes sense, too.

Additional context

In this workflow, I also often need to reopen the layer info and/or attributes in the query result tree.
