Related: fdo#74242 hook up a selection and caret change for multiline edits

a) split the textengine selection changed broadcast into a text selection changed
and text caret change event
b) handle both in existing places that handled the text selection event
c) listen for them in VclMultiLineEdit and translate to
VCLEVENT_EDIT_SELECTIONCHANGED VCLEVENT_EDIT_CARETCHANGED events
d) profit from the VCLEVENT_EDIT_SELECTIONCHANGED and
VCLEVENT_EDIT_CARETCHANGED handling in
accessibility/source/standard/vclxaccessibleedit.cxx for VCLXAccessibleEdits
