Show function symbols in workspace symbols

[musjj]

On VS Code, workbench.action.gotoSymbol shows functions, consts, etc. for the current file, but workbench.action.showAllSymbols only shows structs and nothing else.

By default, in workspace search we only show types, because they are "more important". If there are no matching types we do show functions. You can also set the setting "rust-analyzer.workspace.symbol.search.kind": "all_symbols" to always include functions. In other editors, you can append # to the query (foo#) to search for functions. Unfortunately, in VSCode it does not work, and this is not something we control. The issue tracking improvements to LSP to allow us to do this in VSCode is microsoft/language-server-protocol#2091. You can upvote it, perhaps it will help.
