Rollup merge of #142485 - mu001999-contrib:dead-code/adt-pattern, r=petrochenkov 
Marks ADT live if it appears in pattern

Marks ADT live if it appears in pattern, it implies the construction of the ADT.
1. Then we can detect unused private ADTs impl `Default`, without special logics for `Default` and other std traits.
2. We can also remove `rustc_trivial_field_reads` on `Default`, and the logic in `should_ignore_item` (introduced by rust-lang/rust#126302).

Fixes rust-lang/rust#120770

Extracted from rust-lang/rust#128637.
