Use deferred window positioning in wxWindow::Layout() in wxMSW.

Browse Source 
Ensure that {Begin,End}RepositioningChildren() are called before/after
changing the positions of multiple children, whether we're using sizers or
constraints.

This fixes display corruption which could happen under Windows 7 and a child
resized first became bigger, pushing off the children resized later.

Closes #15214.
