[Bug] GUI should use its own history and not Bash's

[wenzeslaus]

Describe the bug
Every shell is using its own history file. GUI should do that too, but instead it is using .bash_history file. This does not even work across different platforms or shells, it syncs with Bash, but does not with Z shell or others which now more relevant when macOS switched to Z shell from Bash.

Expected behavior

wxGUI (or the Console specifically) is another "shell", so it should keep history in .wxgui_history.

I'm suggesting wxgui_history over gui_history because of the idea of specific shell (with potentially different features and history records) and over wxgui_console_history because the idea in wxGUI is anyway to run all the user-issued commands through the console.

System description (please complete the following information):

• Operating System:
  • Windows (no conflict with Bash at this point I guess)
  • Linux with Bash (shared with bash now, will change behavior)
  • macOS with Z shell (no change of behavior, but clarification of files in mapset)

Additional context

See discussion in #930 which triggered this: #930 (comment).

I'm going to start to look at this :)

Should this be targeted for 8.0.0 instead, since we have a PR that fixes it?
