[WebAuthN] Implement FIDO AppID extension
https://bugs.webkit.org/show_bug.cgi?id=143491
<rdar://problem/48298273>

Reviewed by Brent Fulgham.

Source/WebCore:

This patch adds support for FIDO AppID extension: https://www.w3.org/TR/webauthn/#sctn-appid-extension.
To be noticed, this implementation follows what spec suggested in the 'Note' session and what Chrome/Firefox
do in practice to avoid some unnecessary steps of
https://fidoalliance.org/specs/fido-v2.0-id-20180227/fido-appid-and-facets-v2.0-id-20180227.html#determining-if-a-caller-s-facetid-is-authorized-for-an-appid.

In fido::convertToU2fSignCommand, the checkOnly flag is deleted as it is never used.

Covered by new tests in existing files.

Source/WebKit:

In U2fHidAuthenticator::continueSignCommandAfterResponseReceived, it will retry the current command
with the AppID if it exists when SW_WRONG_DATA is received from devices. Noted, it will not set
the AuthenticationExtensionsClientOutputs::appid to false in any circumstances. In other words, the
field will be empty if AppID is supplied in AuthenticationExtensionsClientInputs and not used.

         Rebaseline the test after r243175. It got somehow landed with failing expectations.

+        [WebAuthN] Implement FIDO AppID extension
+        https://bugs.webkit.org/show_bug.cgi?id=143491
+        <rdar://problem/48298273>
+
+        Reviewed by Brent Fulgham.
+
+        This patch adds support for FIDO AppID extension: https://www.w3.org/TR/webauthn/#sctn-appid-extension.
+        To be noticed, this implementation follows what spec suggested in the 'Note' session and what Chrome/Firefox
+        do in practice to avoid some unnecessary steps of
+        https://fidoalliance.org/specs/fido-v2.0-id-20180227/fido-appid-and-facets-v2.0-id-20180227.html#determining-if-a-caller-s-facetid-is-authorized-for-an-appid.
+
+        In fido::convertToU2fSignCommand, the checkOnly flag is deleted as it is never used.
+
+        Covered by new tests in existing files.

+        In U2fHidAuthenticator::continueSignCommandAfterResponseReceived, it will retry the current command
+        with the AppID if it exists when SW_WRONG_DATA is received from devices. Noted, it will not set
+        the AuthenticationExtensionsClientOutputs::appid to false in any circumstances. In other words, the
+        field will be empty if AppID is supplied in AuthenticationExtensionsClientInputs and not used.
