Fix handling of Esc while an auto-complete drop down is open in wxMSW.

Just close the drop down instead of closing the dialog the text control using
this auto-complete drop down is in, as this was completely unexpected and
counter-intuitive.

Closes #13945.

Fix handling of controls in vertical toolbars in wxMSW.

Not adding the controls to vertical toolbar is not enough, we also need to
hide them to prevent them from being shown as independent floating windows.
And we also need to add separators instead of the controls themselves to keep
the indices the same as in the horizontal case.
