Provides a mechanism to obtain const TypeHandler& references without needing to inject them via jsg argument injection.
tests were implemented by claude with a bit of manual intervention.
This approach is imperfect, of course... specifically because it requires individual types to be registered. It won't automatically work for things like
const TypeHandler<jsg::Promise<T>>since it can't know about all possiblejsg::Promise<T>'s we might use, but it's good enough to investigate the utility.** THIS IS CURRENTLY JUST AN EXPLORATION OF OPTIONS **
Draft since this is still WIP/being investigate.
Internal build will fail until the same v8 patch is landed there.
