Remove the dead code that performs an early return with `if bases == (object,)` in `_coclass_meta`.

[junkmd]

Whether it’s a remnant of Python 2.x or a legacy from the early stages of this project, there is dead code as shown below.

https://github.com/enthought/comtypes/blob/d80810b50eb642053b8dc1c3a2a4735bedf0a059/comtypes/_meta.py#L44-L62

If it can be confirmed that removing it poses no problems, I believe the codebase would be more readable without this section.

     # the coclass' _com_interfaces_ list.
     def __new__(cls, name, bases, namespace):
         self = type.__new__(cls, name, bases, namespace)
-        if bases == (object,):
-            # HACK: Could this conditional branch be removed since it is never reached? 
-            # Since definition is `class CoClass(COMObject, metaclass=_coclass_meta)`,  
-            # the `bases` parameter passed to the `_coclass_meta.__new__` would be      
-            # `(COMObject,)`.
-            # Moreover, since the `COMObject` derives from `object` and does not specify
-            # a metaclass, `(object,)` will not be passed as the `bases` parameter      
-            # to the `_coclass_meta.__new__`.
-            # The reason for this implementation might be a remnant of the differences  
-            # in how metaclasses work between Python 3.x and Python 2.x.
-            # If there are no problems with the versions of Python that `comtypes`
-            # supports, this removal could make the process flow easier to understand.
-            return self
         # XXX We should insist that a _reg_clsid_ is present.
         if "_reg_clsid_" in namespace:
             clsid = namespace["_reg_clsid_"]

This seems to be dead code, because, as we can see in the coverage, the if is never entered.

Thank you for the investigation! With multiple confirmations that this code block seems safe to remove, this is a straightforward good first issue for anyone to tackle.
