Subject: [PATCH] [LLDB] Add minimal support for the new Mojo language

Modular just announced a new language called Mojo. This patch adds an entry in the language list in LLDB for minimal support (e.g. being able to create a TypeSystem for this language). We will later add debug info entries when the language matures.
