Subject: [PATCH 1/3] [lldb][progress][NFC] Add unit test for progress reports

This test is being added as a way to check the behaviour of how progress
events are broadcasted when reports are started and ended with the
current implementation of progress reports. Here we're mainly checking
and ensuring that the current behaviour is that progress events are
broadcasted individually and placed in the event queue in order of
their creation.

Subject: [PATCH 2/3] Simplify set up, remove timeouts, add license

Uses `SubsystemRAII` to initialize the necessary platform and host
information. Since the debugger cannot be initialized with no
arguments (which is how `SubsystemRAII` will initialize everything), the
debugger will be initialized the usual way. Also removes the thread
timeouts and adds the LLVM license header.

Subject: [PATCH 3/3] Check all events outside of scope, use correct check for
 total

Checks that the progress events were received in order of report
creation and deletion outside of the scope that the events were created
in, also checks for more information from the progress event data.

`IsFinite()` from DebuggerEvents would return true if the total was not
UINT64_MAX. Since we no longer use this to specify that an event has no
total this has been changed to check that the total is not 1.
