Revert "Report parsed key id on SFrame unknown-key decrypt failures"

This reverts commit 43f5a1c963381978d29a2f2b85633bb9ad7303f5.

Reason for revert: Breaks downstream build


Original change's description:
> Report parsed key id on SFrame unknown-key decrypt failures
>
> `ToSframeDecryptFailure` previously mapped `invalid_parameter_error` to
> a `kKeyId` failure with an empty key id, because the Cisco Sframe
> library did not surface the key id parsed from the SFrame header.
>
> The library now returns a dedicated
> `SFrameErrorType::unknown_key_id_error` carrying the parsed key id, so
> the mapping is switched over to it and the key id is propagated into
> `SframeDecryptFailure::KeyId`. Applications listening for
> `SframeDecryptErrorCallback` can now tell *which* key is missing,
> matching
> [SFrameTransformErrorEvent.keyID](https://w3c.github.io/webrtc-encoded-transform/#dom-sframetransformerrorevent-keyid).
>
> `invalid_parameter_error` now falls through to the `kSyntax` default,
> which is the correct classification for a malformed header.
>
> Additional changes:
> - Re-enabled `SframeEncryptorDecryptorTest.DISABLED_DecryptReportsKeyIdErrorForUnknownKey`
>   and tightened it to assert the reported key id equals the encryption key id.
