Tabbed Code Pages in Editor

[sancho2]

Edit:
This is already proposed as an issue (feature request) here.

I think it would be a fantastic upgrade to have tabbed pages for editing GDScript code.
Across the top we already have tabs for scene editing I think it is a no-brainer to do the same with code editing.
Most modern and popular editors like VSCode use tabbed code pages.
Also most if not all popular text editors do the same.
I looked through these discussions and didn't see this one asked for yet.
