Refactor code and change change enum_scope_template test to use class enums. Fix few test cases.

- Change enum_scope_template test to use class enums.
- Move the conversion of void* of ptr in swig wrapper to class pointer to Lib files.
- Synchronize between old and new flow. Old flow to accept newly created objects,
with the use of a new property SWIG_classWrapper to newly created objects.
- ZEND_BEGIN_ARG_INFO_EX to hold exact number of arguments required.
- Fix the constructor overloading bug in the in-house Swig_class_overload_dispatch function
- Add helper function to check if the class is wrapped.
- Add ZEND_ACC_ABSTRACT to virtual functions to make the class abstract.
- Change how wname is selected for staticmemberfn.
- Helper function to get names without namespace getNameWithoutNamespace.
- Fix bugs on class entry level at class handler.
  - Move all entry level code to class handler from class decleration.
  - Checking if base.item is null before using it.
  - Check if the parent class is wrapped before using its class entry.
