Always redraw wxPGProperty after changing its attribute

Because changing some attributes of the property affects the format
of displayed value so the property has to be refreshed whether its
attribute is set through wxPGProperty::SetAttribute()
or wxPropertyGridInterface::SetPropertyAttribute().

Closes #18388.
