[fidl][lsp] Make VSCode extension into an LSP Language Client
The extension maintains its formatting and syntax highlighting, and
also launches an LSP server if the relevant configuration setting is
enabled (on by default).
This CL also includes updates to package-lock.json from running
`npm update && npm install`.
Test: npm install && manually test by launching the extension and
opening/editing/navigating some FIDL files.
