TF-Fuzz:  Initial Crypto support plus remaining SST support

This patch provides "set," "read," and "remove" functionality,
for Crypto keys and policies, plus SST creation-flags and
offsets on SST gets.  Many smaller features added as well,
most importantly being the option to specify PSA constants
by their distintive portion in lower-case, such as
"generic_error" in place of "PSA_ERROR_GENERIC_ERROR".
