chore: migrate vscode settings to editorconfig when possible (#3088)

# Description of Changes

Please provide a summary of the changes, including:

- What was changed
Migrate generic VS Code settings to
[EditorConfig](https://editorconfig.org/) so that other editors/IDEs
that support EditorConfig can benefit from it.
Removed opinionated VS Code settings regarding IDE configuration (e.g.,
auto-save) to allow developers to use the interface they prefer.
