feat: Support multiple tab stops for completions in VSCode Uses the native VSCode support for `SnippetTextEdit`s. Fixes #13229 and fixes #8531. https://github.com/rust-lang/rust-analyzer/assets/13354275/a2d2c033-bb30-4f34-92ca-bf3f4f744cdc This is done in a slightly hacky way, as `vscode-languageclient` can't convert RA's `SnippetTextEdit`s into vscode `SnippetTextEdit`s and will appear to use a [different format](https://github.com/microsoft/vscode-languageserver-node/blob/295aaa393fda8ecce110c38880a00466b9320e63/types/src/main.ts#L1501-L1516) in the future. --- ~~Marked as draft since as-is, this will cause completions to double-indent any multi-line code generated.~~ **Update:** This also fixes up edits so that any multi-line code won't be double-indented.
