Timothy Flynn 61c0f67c8c LibWeb+LibWebVew+WebContent+UI: Add IPC to retrieve the system clipboard 
We currently have a single IPC to set clipboard data. We will also need
an IPC to retrieve that data from the UI. This defines system clipboard
data in LibWeb to handle this transfer, and adds the IPC to provide it.
