Add setting to save modified files after applying a refactoring (#2433)

* Add argument for rename command to preserve tab states of modified files

* Ensure didChange is never sent after didClose

This fixes for example the Pyright warning
LSP-pyright: Received change text document command for closed file <URI>
when a file is saved and closed immediately after changes were applied.

* Convert to user setting

* Missed something

* Ensure didChange is never sent after didClose

This fixes for example the Pyright warning
LSP-pyright: Received change text document command for closed file <URI>
when a file is saved and closed immediately after changes were applied.

* Missed something

* Add test

* Maybe like this?

* Try something else

* Simplify expression to save one unnecessary API call

view.change_count() returns 0 if the view isn't valid anymore (closed),
so we can simply use short-circuit evaluation for this and don't need
the is_valid() API call.

* Exempt Linux

* Small tweak to save an API call

* Revert "Exempt Linux"

This reverts commit 4dd2e91.

* Fix failing test on Linux

* actually this test passes locally with this line uncommented

* Revert, apparently it fails on the CI...

This reverts commit 43ede82.

* try a slightly different approach just to see... test pass locally

* Revert "try a slightly different approach just to see... test pass locally"

the test still fail on the CI

This reverts commit 11c5ecb.

* Add default value into schema

* Update to make it work with new rename panel

* Resolve more merge conflicts
