Add option to use long format for attribute panel title

In June 2021, the Attribute Editor (pqSMTKAttributePanel) was modified to add the attribute resource name to the window title, changing its tab label from “Attribute Editor” to, for example, “Attribute Editor(Analysis1)”. SMTK now appends the attribute resource name only when a new cmake option SMTK_ATTRIBUTE_PANEL_LONG_TITLE is set to ON. This new option is OFF by default, so you will need to explicitly set it ON to resume the previous behavior.
