[3.11] gh-105751, test_ctypes: Remove disabled tests (GH-105826) (#107484) 

* The following tests were disabled since the initial ctypes commit
  in 2006, commit babddfca758abe34ff12023f63b18d745fae7ca9:

  * Callbacks.test_char_p()
  * DeletePointerTestCase.test_X()
  * NumberTestCase.test_perf()
  * StructureTestCase.test_subclass_creation()
  * Tests.test_X() of test_byteswap

* NumberTestCase.test_bool_from_address() was disabled in 2007 by
  commit 5dc4fe09b7.
* Remove check_perf() and run_test() of test_numbers.
(cherry picked from commit 8f10140e74)
