add pruning method: Filter Pruning via Geometric Median for Deep Convolutional Neural Networks Acceleration (#95689)
add `class FPGMStructured`
add `function FPGM_structured()`
add `function _validate_distance_type()`
add `function _compute_distance()`
Implement method mentioned in issue #39765
---
FPGMSparsifier Implement with the new pytorch pruning API torch.ao.pruning.
It is a structured pruning method, and it is added under torch.ao.pruning._experimental. Test cases are added at `test_structured_sparsifier.py`.
