This removes the dependency LLDB API tests have on lldb/third_party/Python/module/unittest2, and instead uses the standard one provided by Python. This does not actually remove the vendored dep yet, nor update the docs. I'll do both those once this sticks. Non-trivial changes to call out: - expected failures (i.e. "bugnumber") don't have a reason anymore, so those params were removed - `assertItemsEqual` is now called `assertCountEqual` - When a test is marked xfail, our copy of unittest2 considers failures during teardown to be OK, but modern unittest does not. See TestThreadLocal.py. (Very likely could be a real bug/leak). - Our copy of unittest2 was patched to print all test results, even ones that don't happen, e.g. `(5 passes, 0 failures, 1 errors, 0 skipped, ...)`, but standard unittest prints a terser message that omits test result types that didn't happen, e.g. `OK (skipped=1)`. Our lit integration parses this stderr and needs to be updated w/ that expectation. I tested this w/ `ninja check-lldb-api` on Linux. There's a good chance non-Linux tests have similar quirks, but I'm not able to uncover those.
