[cmap] Fix CmapSubtable.__lt__ TypeError on Python 3

Remove __dict__ from comparison tuples in CmapSubtable.__lt__().
In Python 3, dict < dict raises TypeError, which caused sorting to
fail whenever two subtables shared the same (platformID, platEncID,
language) combination.

Fixes https://github.com/fonttools/fonttools/issues/4035

Log Message:
-----------
[cmap] Raise error on duplicate (platformID, platEncID, language) at compile time

The OpenType spec requires each (platformID, platEncID, language)
combination to appear only once in the cmap table. Validate this
during compile and raise a clear ValueError listing the duplicates.
