Iterate across multiple files more efficiently with GitHub Copilot Edits Preview

Hey! Aaron from the Visual Studio team here, a few notes on what we've built to help iterate across multiple files:

- Added a planning step before generating code: this provides a summary that highlights affected files and proposed changes, just enough to orient you when reviewing the code-diffs.

- Added tool calling: during the planning phase, we automatically search for relevant files in your codebase that could help with your prompt.

- Added speculative decoding: quickly maps your code diffs inline, in your editor, allowing you to review with all your context. Review each chunk with the TAB key to accept or options to apply/dismiss all at once.

- Added checkpoints: allow safe rollbacks or retry if you've got a new approach.
