[Modules] Introduce ScriptOrModule and HostDefinedOptions

Browse Source 
This patch introduces a new container type ScriptOrModule which
provides the name and the host defined options of the script/module.

This patch also introduces a new PrimitivesArray that can hold
Primitive values, which the embedder can use to store metadata.

The HostDefinedOptions is passed to V8 through the ScriptOrigin, and
passed back to the embedder through HostImportModuleDynamically for
module loading.
