Start removing remaining pm code to package manager

Everything is now moved out of the pm command except for
the various install commands.  I am going to hold of on
those since they require doing some resolution with the
current implementations in the package manager to make
sure they match and behave identically to the implementations
currently in the pm command.  But other than that, everything
in pm is now just redirecting over to "cmd package".

Also fix up some of the dumpsys output of a few other sevices
when asking to print the data for a particular package, so
the "pm dump" command gives a little more sane result.

Test: manual
