S390X Support (#274)
* support for s390x * added z15 T01, T02 model checking * removed z15 checking * removed empty strings * added s390x unit tests * added reference url for hwcaps * moved documentation to S390XFeatures struct, updated copyright date, removed unused include statement * changed num_processors to int * removed newlines from test inputs * scripts: Add bootlin s390x support * cmake(ci): Add s390x support * ci: Add s390x workflow Co-authored-by: Marcos <marcos.araque.fiallos@ibm.com> Co-authored-by: Corentin Le Molgat <corentinl@google.com>
