LOCRDT editeng,sw: yrs peer cursors for editengine

The cursors are represented as integers in yrs as a first step, which
isn't ideal.

Surprisingly EditView doesn't really have functions to correct the
cursor, only ImpEditEngine::UpdateSelections() for the case when nodes
are deleted, apparently there's only one active EditView at a time
typically so it wasn't needed?  Typically the active EditView's cursor
is assigned from a return value of ImpEditEngine.

Add some new functions to correct peer cursors and call them all over
ImpEditEngine; unfortunately UpdateSelectionsDelete() isn't easy to get
working on EditView's actual EditSelection cursor so leave that for the
future...

To fix EE paint of non-active comment, add SwAnnotationWin::Paint()

To get things to paint with "gen", it's enough to invalidate the
SwAnnotationWin, but for gtk3 a queue_draw() must be called, else it's
only painted when clicking on the window.

Cursors are painted in color in SidebarTextControl::Paint()
