Fix printing framework compilation with wxUSE_VALIDATORS=0

Include wx/textctrl.h, required here because wxTextCtrl is used as the
base class of wxPrintPageTextCtrl, explicitly instead of relying on it
being implicitly included by something else, as it happens in the
default build but not when validators are disabled.

Closes #19337.
