1fc5c02a - [LVer][profcheck] explicitly set unknown branch weights for the versioned/unversioned selector (#164507)

[LVer][profcheck] explicitly set unknown branch weights for the versioned/unversioned selector (#164507) We don't have sufficient information to know when the versioned (or unversioned) loop variant will be taken, so we mark the branch as having "unknown" probabilities. Issue #147390
