verstage: use common program.ld for linking

There's no reason to have a separate verstage.ld now
that there is a unified stage linking strategy. Moreover
verstage support is throughout the code base as it is
so bring in those link script macros into the common
memlayout.h as that removes one more specific thing a
board/chipset needs to do in order to turn on verstage.
