[Bug Fix] #augmentitem bypasses augment restrictions (#3332)

* [Bug Fix] #augmentitem bypasses augment restrictions

# Notes
- `Object::HandleAugmentation` did not properly check for `augrestrict` values. This allowed augment restrictions to be bypassed with `#augmentitem` or anything else that uses this method.
- `Client::SummonItem` already properly checked these, so I just broke it out into a `Client::IsAugmentRestricted()` method.

* Update item_instance.h
