gh-123339: Fix cases of inconsistency of __module__ and __firstlineno__ in classes (GH-123613)
* Setting the __module__ attribute for a class now removes the
  __firstlineno__ item from the type's dict.
* The _collections_abc and _pydecimal modules now completely replace the
  collections.abc and decimal modules after importing them. This
  allows to get the source of classes and functions defined in these
  modules.
* inspect.findsource() now checks whether the first line number for a
  class is out of bound.

Fix :func:`inspect.getsource` for classes in :mod:`collections.abc` and
:mod:`decimal` (for pure Python implementation) modules.
:func:`inspect.getcomments` now raises OSError instead of IndexError if the
``__firstlineno__`` value for a class is out of bound.
