• #2934 [IDE] Fix issue when deleting an open file outside the IDE that would crash the language server

• Breaking Minimum version of TypeScript updated to 5.0. TypeSpec is using new features available in TypeScript 5.0 which result in a definition file not parsable by older version. Note that this only affect compiling TypeScript code and is not breaking any JS or TypeSpec code. See more information on typescript 5.0
• Remove mkdirp dependencies and replace with built-in mkdir({recursive: true}).
• Compiler keeps track of the scope where a file is declared(User project, a library or the compiler)
