Fix installation error for ClickOnce SF apps that have an application icon set (#7761)

Installation of ClickOnce app as a Single-File with an Application Icon project property set fails to install.

Include _DeploymentManifestIconFile itemgroup to _ClickOnceFiles itemgroup in Single-File mode.

Verified publish and installation of all ClickOnce configurations (FDD and SC) with WPF and Forms app.

Fixes AB#1555818.
