Make CPWL_Wnd own its pAttachedData.

This requires moving it out of CreateParams, since that must be
a copyable struct, and implies that currently there is some
questionable sharing going on. To resolve this, introduce a
Clone() method so that each window gets its own copy.

Make GetAttachedData() return a const pointer, so that callers
can't free it behind our back.

Tidy initializations along the way.
