Remove the (possibly) 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.

comtypes/comtypes/_meta.py

Lines 44 to 62 in d80810b

	# 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_"]

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