The existing implementation of this AO lives in Interpreter::create(), which makes it impossible to use without also constructing an Interpreter. This patch adds a new Realm::initialize_host_defined_realm() and takes the global object and global this customization steps as Function callback objects. This will be used by LibWeb to create realms during Document construction.
