Following #6496 , this PR adds new getters to the python API, as well as tests for them. This makes toPythonObj simpler.
A future PR will add more getters to the python API.

The existing test for python API grammar is moved to the right location, `yapf`ed, and changed according to the new style of python API tests. Additionally, minor changes are introduced in order to be an exact translation of https://github.com/cvc5/cvc5/blob/master/test/unit/api/grammar_black.cpp
This PR removes the old python api tests for terms from test/api/python/test_term.py and replaces it with a new test file test/python/unit/api/test_term.py. The new test file is obtained by translating test/unit/api/term_black.cpp.
In this PR I only include the tests that pass without requiring any change to the python API. The next PR will add functions to the python API that are currently not supported, along with corresponding tests.
Comment: This was originally done in #6460 on the wrong fork. Now it is re-opened, and addresses all comments given there.
This PR does the following:
1. removes old python sort API test
2. creates a new python sort API test, obtained by translating the (entire) cpp unit test https://github.com/CVC4/CVC4/blob/master/test/unit/api/sort_black.cpp
3. adds support for bags and datatype selectors/testers domain/codomain in the python API.
If building with python bindings, check the pytest is installed, and adds a command to run pytest after the existing make check tests. If built without python bindings, it just uses a null command. Note: the current semantics are such that the pytest tests will not run if the ctest run fails (unless you pass the correct flag to make to continue --ignore-errors I believe). I can look into changing this semantics if that would be preferred.
