PPC/s390: [wasm] Rename more "type" to "kind"

Port 52cc7ba9

Original Commit Message:

    This renames more fields holding "ValueKind" or methods operating on
    "ValueKind" to contain "kind" instead of "type".
    It also renames "is_reference_type" to "is_reference" on both ValueType
    and ValueKind, as the "_type" prefix is kind of implicit from the
    argument.
