[lldb][test] Remove benchmark API tests (#108629)

These benchmarks don't get run as part of the regular API test-suite.
And I'm not aware of any CI running this. Also, I haven't quite managed
to actually run them locally using the `bench.py` script. It looks like
these are obsolete, so I'm proposing to remove the infrastructure around
it entirely.

If anyone does know of a use for these do let me know.
