LibGUI+WindowServer: Store the source process' PID in the Window classes

Browse source 
The "Window" classes in LibGUI and WindowServer now store the PID of the
process that created the window. LibGUI's Window obtains the PID in the
constructor via getpid(), and passes it in Window::show() to
WindowServer via the create_window() IPC route. WindowServer then saves
it in its own Window class.
This allows us to find the process that created a window in order to add
process-specific actions to the window.
