Rollup merge of #100780 - wonchulee:translation_save_analysis, r=davidtwco

save_analysis: Migrate diagnostic

* Migrate the `rustc_save_analysis` crate's diagnostic to translatable diagnostic structs.

Depends on https://github.com/rust-lang/rust/pull/100694 and https://github.com/rust-lang/rust/pull/100754 for #[fatal(..)] support, then https://github.com/rust-lang/rust/commit/aa68eb4179881ed25106e675a6a224746f8fad5f, https://github.com/rust-lang/rust/commit/f5219a396083b764f3741e9e105685323a745ce8, https://github.com/rust-lang/rust/commit/7da52f694a4ff7c4b9870415584f2c86cec5ce62 can be removed. (I copied commits from https://github.com/rust-lang/rust/pull/100754)
