This CL factors out the decision-making logic whether a property key should
be treated as a "property" or "element" into LookupIterator::Key, which can
be constructed on its own, allowing use sites to take this distinction into
account before constructing a LookupIterator from the Key, without needing
to duplicate the logic.
This also makes the assortment of LookupIterator constructors more uniform.

Inferring the language mode involves iterating the stack to find the
closure. This is an expensive operation and should be done only when
required. This cl changes the implementation to infer the language
mode only when we can't defer it any further. Currently, we infer the
language mode when throwing an exception or when passing this
information to PropertyCallbackArguments.
This cl also changes the language mode parameter to SetProperty
related methods to Maybe<ShouldThrow>. We only use the language mode to
decide if we need to throw and using ShouldThrow instead of language
mode simplifies the code by avoiding conversions from Maybe<ShouldThrow>
to Maybe<LanguageMode> and vice-versa.
