* [REFACTOR][PY][API-CHANGE] Remove legacy python files. Remove legacy python files. Use the te namespace for most of the tensor expression primitives. - tvm.create_schedule -> tvm.te.create_schedule - tvm.placeholder -> tvm.te.placeholder - tvm.compute -> tvm.te.compute * Remove top-level exposures.

* [REFACTOR][RUNTIME] Move NDArray to Object System. Previously NDArray has its own object reference counting mechanism. This PR migrates NDArray to the unified object protocol. The calling convention of NDArray remained intact. That means NDArray still has its own type_code and its handle is still DLTensor compatible. In order to do so, this PR added a few minimum runtime type detection in TVMArgValue and RetValue only when the corresponding type is a base type(ObjectRef) that could also refer to NDArray. This means that even if we return a base reference object ObjectRef which refers to the NDArray. The type_code will still be translated correctly as kNDArrayContainer. If we assign a non-base type(say Expr) that we know is not compatible with NDArray during compile time, no runtime type detection will be performed. This PR also adopts the object protocol for NDArray sub-classing and removed the legacy NDArray subclass protocol. Examples in apps/extension are now updated to reflect that. Making NDArray as an Object brings all the benefits of the object system. For example, we can now use the Array container to store NDArrays. * Address review comments

Before the unified object protocol, we support pass additional extension objects around by declaring a type as an extension type. The old extension mechanism requires the types to register their constructor and deleter to a VTable and does not enjoy the benefit of the self-contained deletion property of the new Object system. This PR upgrades the extension example to make use of the new object system and removed the old Extension VTable. Note that the register_extension funtion in the python side continues to work when the passed argument does not require explicit container copy/deletion, which covers the current usecases of the extension mechanism.
