LibJS: Set prototype of GlobalObject to ObjectPrototype
...

LibJS: Don't change offset when reconfiguring property in unique shape
...
When changing the attributes of an existing property of an object with
unique shape we must not change the PropertyMetadata offset.
Doing so without resizing the underlying storage vector caused an OOB
write crash.
Fixes #3735 .
