qmake vcxproj generator: write PrimaryOutputExtension value

Second attempt. MSVCPROJ_TARGET contains the resolved target name,
including version number and target extension.
We're splitting this value into PrimaryOutput and
PrimaryOutputExtension.
PrimaryOutputExtension is only written if it contains a non-default
value.

Task-number: QTBUG-26782
