cc rust-lang/libs-team#242 (comment)

This moves over some docs from the rust-lang/rust README (will make a PR there shortly) as well as consolidating existing docs in the guide.

As a followup, I'd like to change the docs to consistently use ./x instead of ./x.py, since it's the most likely to work on every system.

…hapter

Splitting the two was confusing and meant that similar information was in wildly different parts of the guide. Combine them into a single page.
mostly this just suggests using a tracking issue instead of inlining the info from the issue template
I'm going to make a follow-up PR shortly linking from rust-lang/rust to the dev guide so this info isn't duplicated.

Move some docs from the README to the dev-guide

and as a drive-by cleanup, improve the error message for `x test tidy` when a feature gate is missing.

This also improves the error message you get on Windows if python isn't installed.

would asking people to install x crate be too much, given the advantage of not needing to be in repo root to use it

not everyone wants to install a global tool - see https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/bootstrap.20user.20survey/near/283239913. it also doesn't work for distros or anyone else who doesn't already have a global rust toolchain.

👋 would appreciate a review - rust-lang/rust#113008 removed the entrypoint docs from the README so it would be nice to have them in the guide. i can split the entrypoint docs into a separate PR if you prefer.
