ProjectExplorer: De-duplicate code in IBuildStepFactory derived classes

Browse Source 
This removes 900 lines of duplicated code, some duplicated checks at
runtime and some (minor) quadratic behavior when gathering display names.

canClone(), canRestore() and canCreate() and restore() use the same
pattern. Handle that on the core side once. Leave retore() virtual to let
the ios code unmodified (which is likely not needed, later...). Introduce
'Unclonable' and 'Uncreatable' flags to keep Android package installation
and WinRT deployment (non-)functionality unchanged.
