cli: cleanup build

- Remove the `prepare` script entirely
- Variables are now populated from the product.json during build. Most
  variables are mapped automatically, with some special handling in a
	few cases. `build.rs` is now much more self-contained.
- Look for the `product.overrides.json` for vscode developers instead of
  looking for a peer `vscode-distro` folder

Fixes #178691
