moveconfig: Allow control of which implying configs are shown

Browse source 
Sometimes it is useful to display CONFIG_TARGET or CONFIG_CMD configs. Add
an option to control this.

Also we generally ignore implying configs which affect fewer than 5
boards. But sometimes it is useful to show those those, so add an option
that reduces the minimum to two.

ERRATUM configs are never useful for implying things, so ignore those.
