Michael Weghorn f26084217a weld: Move weld::Button to own header/Rename weld.hxx 
In the past, weld.hxx used to contain the class
definitions for weld::Widget and all subclasses.

By now, weld::Widget and almost all subclasses have
been moved to separate headers, to make it easier
to keep the overview and to avoid having to
recompile ~all UI code when one class changes.

By now, only weld::Button is left in weld.hxx.
Rename the header to Button.hxx.
Drop weld.hxx includes and instead add Button.hxx
includes (or weld::Button forward declarations) where
weld::Button is used.
(Don't simply replace all weld.hxx includes with
Button.hxx ones, since many of them were for the
use of other widgets that have since been moved
to their own headers.)

Add further includes where needed now that the
(direct or transitive) includes of weld.hxx were removed.
