Adds support for zone allocated (off-heap) ConsumedPreParsingScopeData to enable worker-thread access to PreParsingScopeData during parallel IIFE compile tasks. In order to avoid code-duplication, a templated BaseConsumedPreParsingScopeData is added which implements the logic for decoding the bytestream into scope data. Two implementations of this base class are instantiated for each of the underlying serialized scope date: - ZoneConsumedPreParsedScopeData for exposing ZonePreParsedScopeData - OnHeapConsumedPreParsedScopeData for exposing on-heap PreParsedScopeData The interface for each of these classes is the ConsumedPreParsingScopeData, which exposes the methods required by the parser to deserialize the required data. As a side-cleanup, moved Ucs2CharLength and Utf8LengthHelper implementations to cc file so that we don't get a linker error if one of them are unused by the cc file including the header.
