c2eb7f213a migration: improve documentation of postcopy-ram 
This capability must have the same value on both source and destination,
otherwise migration fails (commit 875fcd013a "migration: incoming
postcopy advise sanity checks").

Let's write it down in various places where postcopy-ram is documented.

on types that are larger than the host pointer type.
