[plug-in]Delegate showReferences command to textEditor.commands.showReferences

[svor]

The command to show references is already registered by id textEditor.commands.showReferences. But plugins know nothing about textEditor.commands.showReferences id, they use editor.action.showReferences to show references.

To make it possible to execute editor.action.showReferences from the plugin and don't break existing clients we need to delegate editor.action.showReferences to existing textEditor.commands.showReferences command in plugin-ext-vscode.

The command is called, for example when executing the "references" code lens.

Actually, there seems to be a metric boatload of commands that are predefined in VS Code: https://code.visualstudio.com/api/references/commands
