Remove psa-migration/strategy.md
This document is mainly about a plan that was driven by backward
compatibility constraints that no longer exist in 4.0.
Although some of it is still of interest to explain why 4.0 is the way
it is (and more complicated than one would expect based on the APIs that
are left in 4.0). But for this it should suffice to consult earlier
versions and does not worth to maintain it.
