pane: Improve close active item to better handle pinned tabs (#23488)

Closes #22247

- [x] Do not close pinned tab on keyboard shortcuts like `ctrl+w` or
`alt+f4`
- [x] Close pinned tab on context menu action, menu bar action, or vim
bang
- [x] While closing pinned tab via shortcut (where it won't close),
instead activate any other non-pinned tab in same pane
- [x] Else, if any other pane contains non-pinned tab, activate that
- [x] Tests
