feature: Enhanced Identification of `trouble.nvim` Mode

Did you check the docs?

• [X] I have read all the trouble.nvim docs

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

It would be valuable to determine the mode in which the trouble.nvim window is currently opened. For instance, I would like to display in my winbar whether the trouble window currently contains my quickfix list, location list, or workspace diagnostics. When I work with, for example, workspace diagnostics and my quickfix list simultaneously, and switch between them, it can be quite confusing not to have clear visibility into which one is currently displayed in the trouble window.

Describe the solution you'd like

Include information about the mode in the bufname

The filetype should remain consistent for all trouble windows.

When utilizing edgy.nvim, one could write a filter function that specifically targets buffers with e.g bufname == "ToubleQuickfix" and then assign a title like title = "Trouble Quickfix" to be shown in the winbar

Describe alternatives you've considered

Provide an API function such as require("trouble").get_mode()
