Break circular includes between fpdfsdk/ and fpdfsdk/pwl.

The CPWL_Wnd::PrivateData interface replaces all use of
CPDFSDK_Widget at the pwl/ layer. In turn, IPWL_SystemHandler
can no longer use a widget, so it must use PrivateData instead.
This then hits the "no forward declaration of nested classes"
gotcha, so PrivateData moves to IPWL_SystemHandler and is renamed
PerWindowData.
