VS: Add a source file property to mark content for Windows App deployment

Create a VS_DEPLOYMENT_CONTENT source file property, supporting
generator expressions, to compute whether a source file should be marked
as DeploymentContent or ExcludedFromBuild in Windows Phone and Windows
Store projects.

+VS_DEPLOYMENT_CONTENT
+---------------------
+
+Mark a source file as content for deployment with a Windows Phone or
+Windows Store application when built with a Visual Studio generator.
+The value must evaluate to either ``1`` or ``0`` and may use
+:manual:`generator expressions <cmake-generator-expressions(7)>`
+to make the choice based on the build configuration.
+The ``.vcxproj`` file entry for the source file will be
+marked either ``DeploymentContent`` or ``ExcludedFromBuild``
+for values ``1`` and ``0``, respectively.
