Hmm seems like we can't currently run `dotest-param='--category'` on the API test suite because of the simulator tests:
```
 File "/home/runner/_work/llvm-project/llvm-project/lldb/packages/Python/lldbsuite/test/test_result.py", line 183, in startTest
    self.hardMarkAsSkipped(test)
  File "/home/runner/_work/llvm-project/llvm-project/lldb/packages/Python/lldbsuite/test/test_result.py", line 162, in hardMarkAsSkipped
    getattr(test, test._testMethodName).__func__.__unittest_skip__ = True
AttributeError: 'functools.partial' object has no attribute '__func__'. Did you mean: '__doc__'?
```

Looks like the mechanism by which we mark tests skipped doesn't work for the partial methods we construct for the `libcxx-simulators`. Even unwrapping the `functools.partial` method (or adding a separate `categories` file), will silently run these tests. One option would be to add `--filter-out=libcxx-simulators` to the lit-invocation. @labath are you familiar enough with the `unittest` python library to know how to properly mark these simulator tests skipped?
