[GTK][a11y] Connect UI process a11y tree with the web process when building with ATSPI
https://bugs.webkit.org/show_bug.cgi?id=230255
Reviewed by Adrian Perez de Castro.
Source/WebCore:
Add AccessibilityAtspi class to connect to the ATSPI DBus service using the address provided. Also add
AccessibilityRootAtspi class that will be the parent object of the accessibility root wrapper, and the children
of the UI process web view. In ATK the AtkSocket and AtkPlug use a private DBus message to send the unique name
of the UI process connection to the web process. That's not possible with GDBus, so we wait for the first
GetState message to be received (which is called right after atk_socket_embed() is called in the UI process) to
get the unique name of the UI process connection. PlatformDisplay has now API to get the DBus address of the
ATSPI service. This is used only in the UI process that sends the address to the web process, so that we don't
need to get it on every web process again.

Source/WebKit:
Change BindAccessibilityTree IPC message API to have an async reply. When using ATSPI the UI process replies to
the message including the object path of the AtkSocket, to be used by the web process root object as its parent
property (building the reference with the UI process unique name we get from GetState message).
