Martin Storsjö 403cd574b6 [LLDB] [Windows] Fix Windows-specific race condition in LLDB for session lifetime
This can e.g. happen if the debugged executable exits before the initial
stop, e.g. if it fails to load dependent DLLs.

Add a virtual destructor to ProcessDebugger and let it clean up the
session, and make ProcessWindows::OnExitProcess call
ProcessDebugger::OnExitProcess for shared parts.

Fix suggestion by Adrian McCarthy.

Aleksandr Urakov 6179c0eb0d [Windows] Add support of watchpoints to `ProcessWindows`
Summary:
This patch adds support of watchpoints to the old `ProcessWindows` plugin.

The `ProcessWindows` plugin uses the `RegisterContext` to set and reset
watchpoints. The `RegisterContext` has some interface to access watchpoints,
but it is very limited (e.g. it is impossible to retrieve the last triggered
watchpoint with it), that's why I have implemented a slightly different
interface in the `RegisterContextWindows`. Moreover, I have made the
`ProcessWindows` plugin responsible for search of a vacant watchpoint slot,
because watchpoints exist per-process (not per-thread), then we can place
the same watchpoint in the same slot in different threads. With this scheme
threads don't need to have their own watchpoint lists, and it simplifies
identifying of the last triggered watchpoint.

Aaron Smith 9c01eaff6a Move common functionality from processwindows into processdebugger
Summary:
This change extracts functionalities from processwindows into a
introduced processdebugger that can be reused in native process
debugging. 

The main reason is that the native process debugging
can't directly be based on processwindows or be implemented
as a pass-through to this plugin since the plugin has ties to
Target and Process classes that are needed in host debugging but
not necessary in native debugging.
