[JSC] Track stack materialization in in Error.captureStackTrace
https://bugs.webkit.org/show_bug.cgi?id=305789
rdar://168941975
Reviewed by Yusuke Suzuki.
Error.captureStackTrace defines a .stack own property. If this happens on an
ErrorInstance before info is materialized, then when it is materialized, the
.stack defined by Error.captureStackTrace will be overwritten.
This PR adds a bit that avoids materializing .stack properties on
ErrorInstances that had Error.captureStackTrace on them before materialization.
