Michael Weghorn f1f6a505a0 weld: Pass weld::TextWidget& in text change callback/handler 
Switch the weld::Entry and weld::TextView handlers
that are called when the text changes due to user
interaction to pass a weld::TextWidget& param
instead of a weld::Entry& and weld::TextView&
one respectively.
Adjust related methods across the code base accordingly.

This unifies the behavior for both of these
weld::TextWidget subclasses and prepares for
deduplicating the logic and moving it to the
common base class in an upcoming commit.

That will also ensure they stay in sync.
(Change also motivated by the fact that their behavior was
differing before
