Apply "Language" preference change to all windows and components

[per1234]

Describe the request

The "Language" menu of the File > Preferences dialog now offers a selection of languages the Arduino IDE user interface can be localized to (#941).

🙂 The ideal user experience would be for localization to take effect universally immediately after the user changes this preference:

• All open windows
• Arduino CLI output

Describe the current behavior

1. Select File > New from the Arduino IDE menus.
2. Select File > Preferences... from the Arduino IDE menus.
3. Select a different language from the "Language" menu.
4. Click the OK button.
5. Wait for the window reload to finish.

🙁 The UI of other open IDE windows are still localized for the previous language preference:

1. Select Sketch > Verify/Compile from the Arduino IDE menus.
2. Wait for compilation to finish.

🙁 The messages from Arduino CLI shown in the "Output" view are still localized for the previous language preference:

I'm experiencing the same symptoms with Arduino IDE 2.0.3.

English was already set as the interface language, so I haven't actually changed anything to observe this issue.
