[ShadowRealm] Make CallSite#getFunction/getThis throw

Browse Source 
ShadowRealms have a callable boundary: there cannot be any edges between
objects in the ShadowRealm and those from other realms. V8's
prepareCallStack API breaks this invariant via getFunction() and
getThis(). This CL makes those functions throw when called inside
ShadowRealms.
