Convert commits that modify VSCode upstream into patch files

MR: refactor: Convert vscode changes to patch files (!85 - merged)

Description

As part of transitioning to a patch-based strategy to apply changes to the VSCode upstream repository, we want to generate patch files for every commit in the VSCode fork repository that changes the VSCode upstream repository.

Acceptance criteria

• Identify opportunities to drop commits that aren't useful anymore.
• Each patch represents an atomic change. Identify commits that should be squashed to achieve this goal.
