The current implementation of vm LoadConst instruction attempts to call CopyTo method to allocate memory on device for each invocation. This is not problematic for execution on CPU as the constant pool always stores the allocated objects. However, this is very expensive when we perform inference on GPU as CopyTo needs to allocate device memory every time.

This PR introduces a runtime time constant pool to cache the allocated device memory and reuse it whenever possible. For example, the memory will be setup during warmup and inference will not allocate new device memory any more. It reduces the inference time of MXNet ResNet-50 V1 from 57ms to 16+ms on P2.

* [REFACTOR][NODE][RUNTIME] Move Node to the new Object protocol.

This PR removes the original node system, and make node as a subclass of Object.
This is a major refactor towards a better unified runtime object system.

List of changes in the refactor:

- We now hide data_ field, use Downcast explicitly to get a sub-class object.
- Removed the node system FFI in python.
- Removed the node C API, instead use PackedFunc for list and get attrs.
- Change relay::Op::set_attr_type_key(attr_key_name) to relay::Op::set_attr_type<AttrType>().
  - This change was necessary because of the new Object registration mechanism.
  - Subsequent changes to the op registrations
  - The change revealed a few previous problems that is now fixed.
- Patched up a few missing node type registration.
  - Now we will raise an error if we register object that is not registered.
- The original node.h and container.h are kept in the same location.
- Calling convention: kObjectHandle now equals the old kNodeHandle, kNodeHandle is removed.
- IRFunctor now dispatches on ObjectRef.
- Update to the new type checking API: is_type, derived_from are replaced by IsInstance.
- Removed .hash member function, instead use C++ convention hasher functors.

* Address review comments

* [CI] Move golang tests to the end (apache#4164)

* Add support for quantized multiply to Relay (apache#4141)

This patch adds multiply operator for quantized tensors.
The details of the quantized multiplication are outlined
in the code.

This builds on pull request 3927 and includes the changes
