ns for fx: add support for lstm activation matching (#53779)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/53779
Moves the test case for LSTM activation matching to new NS APIs.
This requires adding the ability to log non-Tensor types.
Since we need Loggers to be scriptable and TorchScript does
not support `Union`, we collect statistics in a separate collector
if we have an RNN. Note: this can scale to a small N of
return types, but not to a large N. If the N becomes large in
the future, we will solve it then.
Test Plan:
```
python test/test_quantization.py TestFXNumericSuiteCoreAPIsModels
```
