  [JSC] Handle unknown annotations in Temporal strings
https://bugs.webkit.org/show_bug.cgi?id=223166

Reviewed by Yusuke Suzuki.

This is part of a normative change to the Temporal proposal:
https://github.com/tc39/proposal-temporal/pull/2397
This change stops assuming that all calendar annotations have the `u-ca`
key, and instead parses the key according to the grammar in the spec
text. Unknown annotations are ignored unless they have the `!` flag, in
which case they cause the string to throw.
