…earth Add expansion to while desugar spans In the same vein as rust-lang#88163, this reverts a change in Clippy behavior as a result of rust-lang#80357 (and reverts some `#[allow]`s): This changes `clippy::blocks_in_if_conditions` to not fire on `while` loops. Though we might actually want Clippy to lint those cases, we should introduce the change purposefully, with tests, and possibly under a different lint name. The actual change here is to add a desugaring expansion to the spans when lowering a `while` loop. r? `@Manishearth`

Before this lint didn't trigger on macros. With rust-lang/rust#88175 this isn't enough anymore. In this PR a `WhileLoop` desugaring kind was introduced. This overrides the span of expanded expressions when lowering the while loop. So if a while loop is in a macro, the expressions that it expands to are no longer marked with `ExpnKind::Macro`, but with `ExpnKind::Desugaring`. In general, this is the correct behavior and the same that is done for `ForLoop`s. It just tripped up this lint.
