Med Ismail Bennani 09ff41a087 [lldb/test] Add events listener helper class to lldbtest
This patch introduces a generic helper class that will listen for
event in a background thread and match it against a source broadcaster.

If the event received matches the source broadcaster, the event is
queued up in a list that the user can access later on.

The motivation behind this is to easily test new kinds of events
(i.e. Swift type-system progress events). However, this patch also
updates `TestProgressReporting.py` and `TestDiagnosticReporting.py`
to make use of this new helper class.
