Summary WebAssembly: Module.customSections test copying

In bug #165159 I forgot to check that the ArrayBuffer obtained is always a new object, not a view onto the old. This is important because modifying the ArrayBuffer shouldn't modify the original custom section (there would also be lifetime issues).

(This is already fixed in the engine (ArrayBuffer::tryCreate copies the payload). Added a regression test that mutates a returned buffer and checks later customSections results are unchanged.)
