PR: Transition Debugger plugin actions to the new Run architecture and cleanup Editor plugin

[impact27]

Description of Changes

• Wrote at least one-line docstrings (for any new functions)
• Added unit test(s) covering the changes (if testable)

• Included a screenshot or animation (if affecting the UI, see Licecap)

• Use the Run plugin for the debugger
• move run settings from editor config to run config
• make run_cell_copy work with the debugger by appending %%debug to the cell copy
• Added buttons in the debugger plugin to start debugging from the debugger plugin
• remove legacy run functions and signals from the editor plugin
• remove focus_to_editor option that was now mostly unused ("Maintain focus in the editor" option has no effect when running cells #17028 and Editor loses cursor focus after running cell when IPython console is detached #3221 are still ok) (It was a strange option anyway because focus_to_editor means "do nothing" and not focus_to_editor means focus to the console)
• move debug-specific code from ipyconsole run function to the debugging plugin
• run_cell doesn't have to deal with run_cell_copy because the copy is run as a selection
• separate extra actions and context modifier (from line is not an extra action but a modifier)

Quick review:

Added buttons in the debugger plugin to start debugging from the debugger plugin

I don't like this change because it makes the interface more complicated and crowded, and the toolbar of the Debugger plugin doesn't look good now:

So, please revert it.

Instead, I'd like to add the "Stop debugging" button (i.e. the blue square one) to the main toolbar, because I think it's missing to quickly stop debugging.

remove focus_to_editor option that was now mostly unused

What happens now if the user wants to run/debug something and move the focus automatically to the IPython console?

This feature doesn't work in the master now, and I am not sure why the user would want the focus to jump around. Wouldn't it make more sense to keep the focus where it is? What would be the usecase if that feature was fixed?

@ccordoba12 I reverted it:

You can launch from the debugger toolbar or the menu

Yeah, I forgot about it. Then it's fine to remove that option.

Thanks @impact27 for your work on this!

This looks almost ready, thanks @impact27!

Besides my small suggestions, please also remove the QGroupBox highlighted in the red square below

Since the tab on which it's placed has the same name, it's a bit redundant to have that QGroupBox now.

One more thing: I noticed that you removed the force_wdir kwarg and I'd like to ask you: why is that not necessary anymore? I thought we needed something like that to run local code in remote kernels.

All the logic is now in run_script

Looks good to me now, thanks @impact27!
