rustc: Lint against `#[macro_use]` in 2018 idioms This commit adds a lint to the compiler to warn against the `#[macro_use]` directive as part of the `rust_2018_idioms` lint. This lint is turned off by default and is only enabled when the `use_extern_macros` feature is also enabled. The lint here isn't fully fleshed out as it's just a simple warning rather than suggestions of how to actually import the macro, but hopefully it's a good base to start from! cc #52043

rustc: Trim down the `rust_2018_idioms` lint group These migration lints aren't all up to par in terms of a good migration experience. Some, like `unreachable_pub`, hit bugs like #52665 and unprepared macros to be handled enough of the time. Others like linting against `#[macro_use]` are swimming upstream in an ecosystem that's not quite ready (and slightly buggy pending a few current PRs). The general idea is that we will continue to recommend the `rust_2018_idioms` lint group as part of the transition guide (as an optional step) but we'll be much more selective about which lints make it into this group. Only those with a strong track record of not causing too much churn will make the cut. cc #52679
