* feat: Add `vscodeipc` subcommand for VS Code Extension

This enables the VS Code extension to communicate with a Coder client.
The extension will download the slim binary from `/bin/*` for the
respective client architecture and OS, then execute `coder vscodeipc`
for the connecting workspace.

* Add authentication header, improve comments, and add tests for the CLI

* Update cli/vscodeipc_test.go
