The following "curves" were added to the 'ec' key type in #36879.

  • NODE-ED25519
  • NODE-ED448
  • NODE-X25519
  • NODE-X448

However, none of these are pure EC curves, for example, Curve25519 does not work with ECDSA, which is one of the reasons why crypto.getCurves() does not include Curve25519. This PR makes these "curves" only recognized from the Web Cryptography API experimental interface.

Fixes #37055

I think this is the only public API change (outside of WebCrypto) from the referenced PR, but I'm not 100% sure. It definitely fixes the problem with generateKeyPair.

I still have to manage to change KeyObjectHandle::InitEDRaw to accomodate for the revert in GetCurveFromName

AFAICT id_ is only used to discern between X25519, X448 and then it throws everything else in the default bucket anyway, therefore returning the specific EC curve ids is not necessary and using GetOKPCurveFromName is ok.
