Co-authored-by: Brian Ng <bng412@gmail.com>

* fix: add loose test case and fix replace condition

* test: add new.target tests for static block

* feat: move new-target replace into thisContextVisitor

defaults to replace new.target, do not replace within function

* feat: simplify thisContextVisitor

remove function visitor since environmentVisitor is skipping arrow function
