#714: UX improvements of the Arduino LS in IDE2

- Debounced the connectivity status update.
 - Silent the output channel for the Arduino LS.
 - Delay the problem markers update with 500ms.
 - Do not update the status bar on every `keypress` event.
 - Debounced the tab-bar toolbar updates when typing in editor.
 - Fixed electron menu contribution binding.
 - Aligned the editor widget factory's API to Theia.
 - Set the zoom level when the app is ready (Closes #1244)
 - Fixed event listener leak (Closes #1062)
