The wrapper used to hold the handle for resource type has just the default copy constructor and assignment operator. This causes clang to insert memcpys when it does an assignment of a resource type. The memcpy then cause optimizations to fail when the memcpy is turned into a load and store of an i64. To fix this, we should define copying of a resource type by adding the operator= and copy constructor. Partially fixes #154669
