add a property that's true iff on a dev machine

[danmoseley]

Something like

<OnDevMachine Condition="'$(ContinuousIntegrationBuild)' != 'true' and '$(OfficialBuildId)' == ''">true</OnDevMachine>

One way this would be useful is if you are adding a new warning that will affect several repos (eg., an obsoletion) and expect it to trigger errors that will will break their builds, PR validation and codeflow. You could instead conditionalize it to only warn/error if OnDevMachine is true. That way devs are immediately broken when it reaches a repo and they quickly push up a PR to fix it. But PR validation and codeflow is not broken. Then a week or two later, you remove the condition.

opening an issue as I don't know where this property would go.

@ViktorHofer can you point to which location I should put this in?
