target/i386: Introduce SierraForest-v2 model
Update SierraForest CPU model to add LAM, 4 bits indicating certain bits
of IA32_SPEC_CTR are supported(intel-psfd, ipred-ctrl, rrsba-ctrl,
bhi-ctrl) and the missing features(ss, tsc-adjust, cldemote, movdiri,
movdir64b)
Also add GDS-NO and RFDS-NO to indicate the related vulnerabilities are
mitigated in stepping 3.
