Instead of directly annotating pexpect-based tests with `@skipIfWindows`, we can tag them with a new `pexpect` category. We still automatically skip windows behavior by adding `pexpect` to the skip category list if the platform is windows, but also allow non-Windows users to skip them by configuring cmake with `-DLLDB_TEST_USER_ARGS=--skip-category=pexpect` As a prerequisite, remove the restriction that `@add_test_categories` can only apply to test cases, and we make the test runner look for categories on both the class and the test method.
