Log:
[clangd] Detect C++ for extension-less source files in vscode extension

Summary:
Extend our extension to support detecting these files as C++ files based on the first
line (`-*- C++ -*-`), it will make clangd work on C++ standard headers
(e.g. iostream).

We use the contributes.languages[1] to enrich the builtin VScode C++
support.
