[tools] Add scripts for compile_commands.json and VSCode

This adds two convenience scripts:
- update-vscode.sh downloads/updates Visual Studio Code
- update-compile-commands.py prepares for code indexers like clangd
  by creating compile_commands.json (for all architectures), updating
  generated sources, and compiling the Torque Language Server.
