kennytm 8601c79aff Rollup merge of #59169 - tmandry:allow-features-flag, r=cramertj 
Add `-Z allow_features=...` flag

Adds a compiler option to allow only whitelisted features.

For projects on nightly that want to prevent feature-creep (and maybe, someday, move off of nightly). Not being able to enforce this has been a problem on Fuchsia and at other big companies.

This doesn't support filtering edition feature flags, but someone is welcome to add that if they need it.

README.md

The syntax crate contains those things concerned purely with syntax – that is, the AST ("abstract syntax tree"), parser, pretty-printer, lexer, macro expander, and utilities for traversing ASTs.

For more information about how these things work in rustc, see the rustc guide:
