General cleanup of test_pydoc (GH-29459)
- Uniform usage of `test.support.requires_docstrings` instead of a local check for `-OO`. - Added `requires_docstrings` to a couple more methods that need it. - Replaced a few instances of `test.test_pydoc` with `__name__` to allow for different methods of running just this test file. - Rewrote `test_server` to run faster and better test the server. - Removed unused import. - Removed unused locals. - Minor whitespace cleanups.
