This PR also introduces built-in tasks for Rust and Elixir. Note that this is not a precedent for future PRs to include tasks for more languages; we simply want to find the rough edges with tasks & language integrations before proceeding to task contexts provided by extensions. As is, we'll load tasks for all loaded languages, so in order to get Elixir tasks, you have to open an Elixir buffer first. I think it sort of makes sense (though it's not ideal), as in the future where extensions do provide their own tasks.json, we'd like to limit the # of tasks surfaced to the user to make them as relevant to the project at hand as possible. Release Notes: - Added built-in tasks for Rust and Elixir files.
