make resume not a default feature in renode
...
this is compensated for in xtask to put it back into
your usual builds, but it allows us to not have it in the
swap config.

add routines for shuttling encrypted data to/from swap RAM region
...
RAM is assumed to be off-chip, and thus the data is encrypted
in the region. We also encrypt it in the Precursor case, even
though it's on-chip, because we want to capture this as a test case
in a known working environment.
Also incorporate some routines to generate the per-boot random
key for swap encryption.
