Detailed description

• Truncates the end of function names by setting a default width for function name columns on startup

• The truncation and default width can be changed in Edit->Preferences->Interface->functions

• Currently affects Functions and Backtrace widget. Only affects Functions widget when its in Horizontal mode. Since vertical/nested mode only has the name column, it seems reasonable not to truncate it

• This PR also cleans the logic for BacktraceWidget to follow the model/view architecture while moving the rizin querying logic from backtrace widget to CutterCore

• For interface related options since there will most likely be a lot more in the future it's better to create a single signal per category so there aren't 100 signals for 100 different options. I mentioned it here because this PR refactors the signals added in Improve inefficient screen space usage #3580 to follow this approach

As much as I would like to handle elision differently such as preserving the function name instead of long mangled arguments lists, it just makes the function name more difficult to understand. Not to mention making a generic function that does elision for binaries written in different languages (C++, rust, java...) is not trivial. Maybe that's why tools like IDA follow the same approach of limiting the function name columns width

Test plan (required)

• Open cutter
  • using binary which contains long function names
  • or add a function with a long name through the console then do View->Refresh
• Observe that the function name column in functions widget is set to a specific width (400 by default) to prevent the next columns from being pushed into oblivion
• Set a breakpoint on that long named function
• Start debug and continue till the break point is hit
• Observe Backtrace widget follows the same width as functions widget
• Go to Edit->Preferences->Interface
• Try changing the width and checking/unchecking the "Limit function name column width to" option
• Observe the width for function name columns for both widget changes
• Try setting the width to 9999, observe the column should resize to contents if the set width is greater than contents width
• Hover on the option in preferences to see the tooltip

Since only the column width is changed and not the displayed text, searching in quick filter should work fine
