Subject: i386: Add new CPU model Cooperlake

Git commit: 22a866b6166db5caa4abaa6e656c2a431fa60726
References: JIRA-SLE-10195

Cooper Lake is intel's successor to Cascade Lake, the new
CPU model inherits features from Cascadelake-Server, while
add one platform associated new feature: AVX512_BF16. Meanwhile,
add STIBP for speculative execution.
