vcl::WindowData is used to manage/store various state
information for windows. It can be (de)serialized to/from string.
So far, both the weld::Window API to get/set window state
as well as the SvtViewOptions API were based on the string
representation.
Switch those and various related places to using vcl::WindowData
instead to use a stronger/more specific type than just OUString
in various places across the code base.
Do the string (de)serialization where necessary, but otherwise
prefer to use vcl::WindowData directly.
Calling weld::Window::set_window_state with a WindowData
param that doesn't indicate that anything should be set
(i.e. whose mask is vcl::WindowDataMask::NONE) should
have no effect, so drop extra checks that were previously
checking whether the string representation was empty
and skipping the call to weld::Window::set_window_state in
that case.
No change in user-observable behavior intended or
seen in a quick test.
