Reviewed by Per Arne Vollan.

Unship support for `Clear-Site-Data: "executionContext"` HTTP header value. We've recently
added support but we're the only browser engine that supports this value. This header value
causes frames from the origin to get reloaded so it can lead to bad consequences if not used
properly. Now that we have evidence of such unexpected reloads on MDN, I think we should
unship for now.
