show StateCache flags in Pkg debug prettyprint

This basically introduces ~33 flags in the output, but a package can
have only ~11 of them displayed at the same time. There is quiet a bit
of duplication also (an uninstalled package is by definition a
newinstall if its getting installed), but as this is debug output we are
better of showing them all in case one of them isn't set in a way it is
supposed to be set.
