ec594dd3 - [ao][sparsity] Bug fix: data not correctly attached to the sparsifier (#80394)

[ao][sparsity] Bug fix: data not correctly attached to the sparsifier (#80394) Issue: Previously, the data was not "attached" to the data sparsifier. Meaning the data sparsifier created a copy of the actual data inside it's container. So, when the data was modified outside of the sparsifier, the changes was not reflected in the sparsifier. Fix: Use register_buffer() instead of nn.Parameter(..) to store the data inside the container. Also, added a unit-test to reference this issue. Test Plan: ```python test/test_ao_sparsity.py TestBaseDataSparsifier``` ```python test/test_ao_sparsity.py TestNormDataSparsifiers``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/80394 Approved by: https://github.com/z-a-f
