PY-72009 Set global debugger after all its fields initialization

Browse Source 
The `set_global_debugger` invocation has been moved to a later point to ensure all debugger fields are initialized first. This addresses potential issues in multithreaded environments where the debugger is accessible, but access to its fields may fail.
