Luau Language Server

Intellisense, code completion, type checking, etc. for Luau files.

As of now, it works but there's still stuff to do:

• Dynamic support for .lua files is currently broken
• Support .luarc, documentation, and global type files
• Add fast flag support?
• Opt-in Roblox globals & api docs
