Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/37032
DataParallel requires all params and buffers of child modules to be updated
in place because of how it implements model replication during the
forward pass (see https://github.com/pytorch/pytorch/pull/12671 for
context). Any params or buffers not updated in place are lost and not
propagated back to the master.
This diff updates (some quantized modules) (TBD: all quantized modules? determine a good cut
point) to do their parameter update in-place. This will enable static
quant and QAT to work correctly with DataParallel.

In graph mode we need to observer the activation tensor for dynamic quantization. This observer should behave the same way as the quantization functions called in the dynamic operator.
Currently for qlinear_dynamic we call quant_utils::ChooseQuantizationParams which has its own logic for calculating scale and zero_point.
We mimic those calculations in the new observer.

This fixes an issue for QAT models. During eval if we call `prepare_qat` and `convert` before calling `load_state_dict` it throws an error because the weight info (num channels) is not updated in the observer module.
It is not an issue for per-tensor case
Fixes issue #33830

Now that the ClassType can be shared among different module instances, we'll
preserve the sharing in clone as well, that is if the original module has
a ClassType that is shared, we'll clone this ClassType once and share it between
different module instances as well.

Summary:
The PR tried to enable the per-channel(row-wise) dynamic quantization for linear operator. Given we have seen some accuracy drop due to the per-tensor quantization, we expect the per-channel could help improve the accuracy.

This fixes the hard-coding of packed parameter values for the dynamic quantized LSTM by orchestrating the following dance:
1) Each variadic parameter on the module has its own Module. That Module defines the `__getstate__` and __setstate__` method s.t. packed weights are properly re-done on model load.
2) Each of these modules is wrapped into a `torch.nn.ModuleList`, s.t. the parameters appear as attributes in the hierarchy. Then, `gatherParametersAndBuffers` (9c43b16df9/torch/csrc/jit/tracer.cpp (L285)) can see these parameters and create a `Value*` for them in the traced graph.
3) In forward, we need to convert from ModuleList -> Module -> Parameter to a simple TensorList of the parameters. We just use a loop here. In tracing, we simply record a `ListConstruct` with each of the proper parameter values. In scripting, the `ModuleList` is const, so it can be unrolled into the graph and a subsequent `ListConstruct` does its business.
The `forward` of the traced LSTM before and after this change are as follows:
Before
```
def forward(self,
input: Tensor,
argument_2: Tuple[Tensor, Tensor]) -> Tuple[Tensor, Tuple[Tensor, Tensor]]:
hx, hx0, = argument_2
_0, _1, _2 = torch.quantized_lstm(input, [hx, hx0], [CONSTANTS.c0, CONSTANTS.c1], True, 1, 0., True, False, False, dtype=12, use_dynamic=True)
return (_0, (_1, _2))
```
After
```
def forward(self,
input: Tensor,
argument_2: Tuple[Tensor, Tensor]) -> Tuple[Tensor, Tuple[Tensor, Tensor]]:
_0 = self.cell._all_weight_values
_1 = getattr(_0, "0").param
_2 = getattr(_0, "1").param
hx, hx0, = argument_2
_3, _4, _5 = torch.quantized_lstm(input, [hx, hx0], [_1, _2], True, 1, 0., True, False, False, dtype=12, use_dynamic=True)
