jetty: hpack header values cause denial of service in http/2

A flaw was found in Jetty http2-hpack and http3-qpack. If header values exceed the size limit and Huffman is the trueMetaDataBuilder.checkSize, the multiplication will overflow, and the length will become negative, causing a large buffer allocation on the server, leading to a Denial of Service Do...
