Improve feature gate and x.py docs - #1701
Conversation
…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.
…s, r=clubby789 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. cc rust-lang/libs-team#242 (comment), rust-lang/rustc-dev-guide#1701

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. |

Looks great, thank you!
I am not going to merge this in case you want more reviews. Feel free to merge anytime though!

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
./xinstead of./x.py, since it's the most likely to work on every system.
