port(v2): Unsaved confirmation dialog for "Open with Encoding" feature

[traeok]

Proposed changes

Backport of the confirmation dialog shown for "Open with Encoding" when trying to change the encoding on an unsaved file.

Note: currently this only reverts the active editor. I'm still looking for a solution that will allow us to revert an editor that isn't active but is open - if anyone is aware of one please let me know 😋

In v3 we use the vscode.window.tabGroups approach to look for an editor in all open tabs, but this is not supported for VS Code versions older than v1.65.

Release Notes

Milestone: 2.17.0

Changelog:

• Added a confirmation dialog when the encoding is changed for an unsaved data set or USS file. #2911
