RFR: 8264864: Multiple byte tag not supported by ASN.1 encoding [v3]

[Weijun Wang]

> This code change does not intend to support multiple byte tags. Instead, it aims to fail more gracefully when such a tag is encountered. For `DerValue` constructors from an encoding (type I), an `IOException` will be thrown since it's already in the throws clause. For constructors from tag and value (type II), an `IllegalArgumentException` will be thrown. All existing type II callers inside JDK use tag numbers smaller than 31.
