Rollup merge of rust-lang#86537 - inquisitivecrystal:mark-edition-tests-check-pass, r=JohnTitor

Mark some edition tests as check-pass

## Overview
This helps with rust-lang#62277. In short, there are some tests that were marked as `build-pass` when it was unclear whether `check-pass` might be more appropriate. This PR marks some of those tests as `compile-pass`, in addition to making some incidental formatting improvements.

## A brief explanation of why this is correct
These tests fall into a few buckets.

`src/test/ui/dyn-keyword/dyn-2015-edition-keyword-ident-lint.rs`
`src/test/ui/dyn-keyword/dyn-2015-idents-in-decl-macros-unlinted.rs`
`src/test/ui/dyn-keyword/dyn-2015-idents-in-macros-unlinted.rs`
`src/test/ui/dyn-keyword/dyn-2015-no-warnings-without-lints.rs`
`src/test/ui/dyn-keyword/issue-56327-dyn-trait-in-macro-is-okay.rs`

These test a lint for a keyword added in a new edition and the corresponding changes in keyword rules.

`src/test/ui/editions/edition-feature-ok.rs`
This checks that a feature related to an edition transition is valid.

`src/test/ui/editions/edition-imports-virtual-2015-ambiguity.rs`
This checks that imports between editions work correctly.

`src/test/ui/editions/edition-keywords-2015-2015-expansion.rs`
`src/test/ui/editions/edition-keywords-2018-2015-expansion.rs`
This checks the interaction between a change in keyword status over editions and macros.

All of the things being tested come before linking and codegen, so it is safe to use `check-pass` for them.
