fix: js-scope refactor - various renames

[francinelucca]

Closes #193

Implements refactors needed for JS scope as per JS Scope low level design mural.

Changelog

New

• js folder under scopes that will hold logic for incoming JS scope functionality.

Changed

• Moved some JsxScope functions into their own function files and located under new "js" scope folder. See JS Scope low level design mural "refactor" section for more details.
• Generalized some functions, interfaces, classes and types so that they can be consumed by both js and jsx scope. See JS Scope low level design mural "refactor" section for more details.

Testing / reviewing

Functionality remains exactly the same, all unit tests should continue to pass and code coverage should be on par with main.
