[webauthn] KeyUsage requirement (Certificate Signing or empty) for attestation roots (#1519)

xbillyj has just created a new issue for https://github.com/w3c/webauthn:

== KeyUsage requirement (Certificate Signing or empty) for attestation roots ==
RP chain build validation of attestation statements can fail if the Key Usage extension is present and does not include "Certificate Signing".

See https://github.com/fido-alliance/mds-ops/issues/4 for related issue. Goal is to avoid vendors errantly publishing roots with non-empty KeyUsage that does not include Certificate Signing.
