s390x/tcg: refactor stfl(e) to use s390_get_feat_block()
Refactor it to use s390_get_feat_block(). Directly write into the mapped
lowcore with stfl and make sure it is really only compiled if needed.
While at it, add an alignment check for STFLE and avoid
potential_page_fault() by properly restoring the CPU state.
Due to s390_get_feat_block(), we will now also indicate the
"Configuration-z-architectural-mode", which is with new SIGP code the
right thing to do.
