Make dict2inst to work with arbitrary _init parameters

Browse source 
This is achieved by skipping initializer call while creating an instance
of a GDScript. This is implemented by passing -1 as an argument count
to `_new` and interpreting any value below 0 to mean that the initializer
should not be called during instantiation, because internal members of
an instance are going to be overridden afterwards.
