Linus Groh 40a70461a0 LibWeb: Replace GlobalObject with Realm in wrapper functions
Similar to create() in LibJS, wrap() et al. are on a low enough level to
warrant passing a Realm directly instead of relying on the current realm
from the VM, as a wrapper may need to be allocated while no JS is being
executed.
