qv4generatorobject: Fix crash when creating new properties

Previously HeapObject::GeneratorObject utilized a ValueArray member to store stack information.
As we rely on all HeapObject members to have a constant size in order for QV4Table::inlinePropertyOffset
to remain accurate, this lead to a memory conflict when a user defined his own property on the Generator.

Please do not use ValueArray for any types that are user accessible or that you intend to add properties to.

Now the stack information is stored into ArrayObjects instead which circumvents the issue.
