✨ Remember Workspace State Per Window

### Describe the solution you'd like

We need to persist workspace state per window after the user quits and opens CodeEdit again.

We will need to also remember
- [x] editor layout
- [x] for each editor
- [x] size (width/height where applicable)
- [x] which tabs/files are open
- [x] which tab is active
- [x] order of tabs
- [ ] the navigator, inspector, and utility areas
- [ ] size (width/height respectively)
- [x] navigator area
- [ ] inspector area
- [ ] utility area
- [x] opened/closed state
- [x] navigator area
- [x] inspector area
- [x] utility area
- [ ] which tab is active
- [ ] navigator area
- [ ] inspector area
- [ ] utility area
- [ ] order of tabs
- [ ] navigator area
- [ ] inspector area
- [ ] utility area
