The proper name of the library is `annotate-snippet`, not `annotate-rs`,
this commit should get rid of any confusing `AnnotateRs` names.

1. Renames `annotate_rs_emitter.rs` to
   `annotate_snippet_emitter_writer.rs` so that the difference between the
   `Emitter` trait and the implementers is more clear.
2. Renames `AnnotateRsEmitterWriter` to `AnnotateSnippetEmitterWriter`
3. Renames `HumanReadableErrorType::AnnotateRs` to `HumanReadableErrorType::AnnotateSnippet`

Changes:
````
rustup rust-lang#57428
Remove `to_string()`s from CompilerLintFunctions
Fix comment grammar
Fix .map(..).unwrap_or_else(..) bad suggestion
add suggestions for print/write with newline lint

rustbuild: Include `rustfmt` in deduplicated dependencies

Currently `rustfmt` is excluded from the "don't build dependencies
twice" check but it's currently building dependencies twice! Namely big
dependencies like `rustc-ap-syntax` are built once for rustfmt and once
for the RLS. This commit includes `rustfmt` in these checks and then
fixes the resulting feature mismatches for winapi.
