Remove `(TypeCheck|SubjectType|PredicateType|ObjectType)Error` and related

Also remove
`check_(context|subject|predicate|object|statement|pattern)`.

It seems nothing is using these exceptions and functions.

Technically this does remove parts of the public API, but I would argue
they are "buggy" parts as anything that use them would be sorely
disappointed to find that the behaviour is not as expect, and these
functions/exceptions don't serve any function related to the aim of
RDFLib unless they are integrated with the rest of RDFLib.
