Create class types for MSVC RTTI

[emesare]

When RTTI analysis finishes we should add another workflow that will create class types from the RTTI information. This already existed in the external plugin here however was omitted for concerns over what exactly RTTI analysis was responsible for.

After further discussion we should aim to add a disabled by default option that when enabled will automatically create class types. These class types can only really be defined with the vtables as no member fields can be inferred as constructor identification is not currently done.

After this is done we should then focus on #6217

After we do #6217 we can circle back around to this and optionally fill in member fields found inside the virtual functions, IMO this should be the users responsibility though and I am hesitant to auto create member fields, especially because ownership over them is not trivial.
