Zachary Turner a32d2cecba [ProcessWindows] Improve support for launching processes.
This sends notifications for module load / unload to the process
plugin, and also manages the state more accurately during the
loading sequence.

Similar work by Virgile Bello was referenced during the
implementation of this patch.

Zachary Turner d6a7b63f26 [ProcessWindows] Simplify the DebugDelegate interface.
Due to a previous multi-threaded design involving message
passing, we used message classes to pass event information
to the delegate.  Since the multi-threaded design has gone
away, we simplify this by passing event arguments as direct
function parameters, which is more clear and easier to
understand.

Zachary Turner dcd80377f3 [ProcessWindows] Implement breakpoint stop / resume on Windows.
This patch implements basic support for stopping at breakpoints
and resuming later.  While a breakpoint is stopped at, LLDB will
cease to process events in the debug loop, effectively suspending
the process, and then resume later when ProcessWindows::DoResume
is called.

As a side effect, this also correctly handles the loader breakpoint
(i.e. the initial stop) so that LLDB goes through the correct state
sequence during the initial process launch.

Zachary Turner 742346a22f Decouple ProcessWindows from the Windows debug driver thread.
In the llgs world, ProcessWindows will eventually go away and
we'll implement a different protocol.  This patch decouples
ProcessWindows from the core debug loop so that this transition
will not be more difficult than it needs to be.
