Windows uninstaller should have option to also remove user data dir and extensions dir

I tried to uninstall / Reinstall Code Insider because of a recurring Error/Crash at “startup/reloaded” (Update / Reboot / proper exit), disabling extensions and remove all custom settings did not fixed it Before re-installing i wanted to be sure i has no crap left that code have hurted Code Insiders … surprise surprise …

• VSCode Version: Latest of Code and Code Insider
• OS Version: Windows 10

Steps to Reproduce:

1. Install it
2. Add extensions
3. Change settings
4. Use it
5. Update it
6. Uninstall it
7. Be curious on what’s left

On top of that, i uninstalled extensions long time ago and they were still on disk, here is what code-insiders --list-extensions output :

Angular.ng-template
bierner.markdown-preview-github-styles
eamodio.gitlens
EditorConfig.EditorConfig
eg2.tslint
formulahendry.dotnet-test-explorer
GitHub.vscode-pull-request-github

do you think adding a check box to the “uninstall” panel to fully clear everything would helps users ?

also “uninstall” for extension would have a new button “uninstall from disk”

this seems like a good idea : https://github.com/microsoft/vscode/issues/66837#issuecomment-517970912

As #76590 (part of #3884) has been on deck recently, I guess #3884 will be assigned as well. After that, this issue #66837 will be possible to fix. I hope these would happen ASAP because I have waited for near two years (actually #3884 has been opened for more than 3 years).
