Focus on the specific element when open in editor

What problem does this feature solve?

In vue 3 we have line and column numbers for AST nodes, so now we can focus on the specific element when opening the editor.

What does the proposed API look like?

Here's a possible approach:

1. Inject location info to props when compiling
2. Send location info to a vscode plugin when hovering on an element
3. Open source files with preview mode in the plugin

Looking forward to this feature for two whole years!
