Rollup merge of #142594 - mejrs:new_desugaring, r=chenyukang
Add DesugaringKind::FormatLiteral Implements `DesugaringKind::FormatLiteral` to mark the FormatArgs desugaring of format literals. The main use for this is to stop yapping about about formatting parameters if we're not anywhere near a format literal. The other use case is to fix suggestions such as https://github.com/rust-lang/rust/issues/141350. It might also be useful for new or existing diagnostics that check whether they're in a format-like macro. cc `@xizheyin` `@fmease`
