Rollup merge of rust-lang#128664 - fuzzypixelz:add-codegen-ssa-debug-impls, r=lcnr

Add `Debug` impls to API types in `rustc_codegen_ssa`

Some types used in `rustc_codegen_ssa`'s interface traits are missing `Debug` impls. Though I did not smear `#[derive(Debug)]` all over the crate (some structs are quite large).
