This PR adds support for selecting toolchains for a given language (e.g. Rust toolchains or Python virtual environments) with support for SSH projects provided out of the box. For Python we piggy-back off of [PET](https://github.com/microsoft/python-environment-tools), a library maintained by Microsoft. Closes #16421 Closes #7646 Release Notes: - Added toolchain selector to the status bar (with initial support for Python virtual environments)

Rust
//! Provides support for language toolchains.
|
|
//!
|
|
//! A language can have associated toolchains,
|
|
//! which is a set of tools used to interact with the projects written in said language.
|
|
//! For example, a Python project can have an associated virtual environment; a Rust project can have a toolchain override.
