Pad queries when EDNS0 is enabled. Behavior is compliant with https://tools.ietf.org/html/draft-ietf-dprive-padding-policy-04 EDNS0 is only enabled when the netcontext requests it, i.e. in DNS-over-TLS mode. Bug: 69623036 Bug: 64133961 Test: Wireshark verified. Integration tests echo padding and pass.
