Description

As noticed in https://github.com/rust-lang/rust/pull/128722#issuecomment-2297605573 when trying to bump cc to a version which drops support for VS 2013.

Also cc:

We also don't document minium versions of binutils etc on the platform support page. Maybe we should! But that's a pre-existing issue and bumping cc or not doesn't change that.

INSTALL.md exists, but that seems more like some general advice for getting started, but not actual documented guarantees in terms of what kind of build environment is supported.

Research direction

Start by reading INSTALL.md and the existing platform support page, then review the linked discussion about cc and VS 2013. Document the exact minimum supported versions of build tools for each relevant Rust toolchain or platform, clearly distinguishing guarantees from general setup advice.
