[lldb] Fix dead lock issue when loading modules in Scripted Process

This patch attempts to fix a dead lock when loading modules in a Scripted
Process.

This issue was triggered by loading the modules after the process did resume,
but before the process actually stop, causing the language runtime mutex to
be locked by a separate thread, responsible to unwind the stack (using
the runtime unwind plan), while the module loading thread was trying to
notify the runtimes of the newly loaded module.

To address that, this patch moves the module loading logic to be done before
sending the stop event, to prevent the dead lock situation described above.
