VS Code setting and extensions in repository

[marnova]

It would be nice to have VS Code settings and recommended extensions at one place and shared between developers.

For this purpose we can create .vscode folder in root of git repository and fill it with settings and recommended extensions.

Recommended extensions Example here - https://tattoocoder.com/recommending-vscode-extensions-within-your-open-source-projects/

Settings Docs for settings - https://code.visualstudio.com/docs/getstarted/settings#_workspace-settings And some tips https://stackoverflow.com/questions/32964920/should-i-commit-the-vscode-folder-to-source-control

We also need to properly set Python and Rust paths.

Note: we still want to preserve .editorconfig, because this issue is related only to VS Code.
