[turbopack] Remove the `_for_input` options from `turbo_tasks::value` and the `TypedForInput` trait. (#80185)
# Remove `auto_for_input` serialization mode from turbo-tasks
This PR removes the `auto_for_input` and `custom_for_input` serialization modes from turbo-tasks, along with the `TypedForInput` marker trait.
These were used for values passed via the `Value<>` type, but that is dead.
