Subject: [PATCH 3/3] Drop sizeAdjustPolicy from the .ui files for Qt4's uic

Qt4's uic emits the property verbatim, which fails to build against Qt4:

  ui_dialogconversionstatus.h:72: error: 'class QTreeWidget' has no member
  named 'setSizeAdjustPolicy'; did you mean 'setSizePolicy'?
  ui_dialogconversionstatus.h:72: error: 'AdjustToContents' is not a member
  of 'QAbstractScrollArea'

QComboBox has had sizeAdjustPolicy since Qt4, but QAbstractScrollArea only
gained it in Qt5.2, and both uses here are on QAbstractScrollArea subclasses:
a QTreeWidget in dialogconversionstatus.ui and a QScrollArea in dialoginfo.ui.

As with stepType, the property is set from code behind a Qt5.2 guard instead,
so Qt5 and Qt6 keep the existing behavior.

A full re-audit of every .ui property against its owning widget class found no
other Qt5-only property, attribute, enum or flag value. The earlier pass missed
this one by assuming sizeAdjustPolicy belonged to the QComboBox that also
appears in these forms.
