[JSC] Expose error messages from ShadowRealms to outer realm
https://bugs.webkit.org/show_bug.cgi?id=249324
Reviewed by Yusuke Suzuki.
This adds stuff from a yet unmerged spec change from
https://github.com/tc39/proposal-shadowrealm/pull/382.
This particular implementation only concerns itself with converting a
primitive exception to a String and using that as the TypeError message,
or else accessing the own "message" property of an object and using
that, which is sufficient to inherit messages from a native Error.
A more robust approach could attempt to load "message" from the
prototype chain, and could incorporate some limited source information
from the source error into the new error message.
