This patch replaces the type of the ProcessLaunchInfo ScriptedProcess
Dictionary from a StructuredData pointer to be serialized in a string.
The reason behind this change is that the lifetime of the dictionary's
pointer could be managed by an actor other than the debugger (i.e. the
Python Interpreter). In some cases, this caused the dictionary's pointer
to point to corrupted memory, which can interfere with the good functionning
of Scripted Processes and Scripted Threads.
This patch also updates the related-code to take these changes into account.
