Rollup merge of #150032 - Kivooeo:annotate-snippets-stable, r=Muscraft

Use annotate-snippet as default emitter on stable

This is implementation of rust-lang/rust#149932

Now, after MCP was accepted, we can use annotate-snippet as default emitter for errors, that means that we not longer need of previous emitter, so this PR removed previous emitter and makes annotate-snippet new default one both on stable and nightly

(this PR does not remove a code of previous emitter it just removes a `Default` option of `HumanReadableErrorType` enum, and keeping only `HumanReadableErrorType::AnnotateSnippet` as it now uses by default)
