Revert "sal_uIntPtr->unsigned long in SystemEnvData"

This reverts commit c0f1d211eff5f89f5c9298743f6e7d91d187b799, which states that
it changed the type of UNX-only SystemEnvData::aWindow from sal_uIntPtr to
unsigned long "to match the type used by X11".  (And while resource IDs used for
windows etc. are apparently 32-bit in the X11 protocol, see e.g.
<https://www.x.org/releases/X11R7.7/doc/xproto/x11protocol.html>, Xlib and the
underlying /usr/include/X11/Xdefs.h indeed appear to be somewhat confused
whether the typedef for XID should be unsigned long (presumably stemming from
times when long was universally 32-bit) or CARD32, see e.g.
<https://gitlab.freedesktop.org/xorg/proto/xorgproto/-/blob/master/include/X11/
Xdefs.h>.)

But at least for GTK3/Wayland, the sal_uIntPtr values returned by
GtkSalFrame::GetNativeWindowHandle (in vcl/unx/gtk3/gtk3gtkframe.cxx, and which
are stored in SystemEnvData::aWindow in GtkSalFrame::InitCommon,
vcl/unx/gtk3/gtk3gtkframe.cxx, and GtkSalObjectBase::Init,
vcl/unx/gtk3/gtk3gtkobject.cxx) as

> return reinterpret_cast<sal_uIntPtr>(gdk_wayland_window_get_wl_surface(pWindow));

are struct wl_surface* values, so sal_uIntPtr looks like the overall more
appropriate type after all.

(The part of c0f1d211eff5f89f5c9298743f6e7d91d187b799 that dropped the somewhat
needless C-style-cast converting aWindow from sal_uIntPtr to sal_IntPtr in
SystemChildWindow::GetParentWindowHandle, vcl/source/window/syschild.cxx, has
not been reverted, though.)
