Fix issues in codebase, multiple new features

* Added `Output.ScriptType`, which denotes the "type" of script that outputs in Studio. (LocalScript/Script/ModuleScript)

* Added "Fast-Flags" to the project file (`Flags`); they're specifc options for Maui's codegen to check and respect at runtime.

* Added `Flags.ContextualExecution`; which denotes if client/server context should be checked at runtime. (Only running `LocalScripts` on the client, only running `Scripts` on the server etc) It also decides the behavior of respecting `LuaSourceContainer.Disabled`, and will run scripts anyway if this option is set to false.

* Added `Flags.ReturnMainModule`; (When applicable), return the contents of a "MainModule"-named `ModuleScript` from the root of the model. This behaves exactly like Roblox's "MainModule" system, like if you were requiring a module by its' ID.

* Fixed a (very recent) issue with the `ScriptDocument:EditTextAsync` method of placing script output into the editor when it's over 200k characters; a recent Roblox API change broke how we handled the output.

* Fixed the `script` global in the project file not being set to itself. (for literal instance returns)

* Overall improvements around the codebase, fixed some issues when internally handling the project file format.
