[quant][fx] Remove should_insert_output_observers (#74775)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74775
We have simplified the way we insert observers, for add_scalar it now behaves the same way
as general_tensor_value ops, which means we only need to keep is_general_tensor_value_op now,
the other methods can be removed
Test Plan:
python test/test_quantization.py TestQuantizeFx
python test/test_quantization.py TestQuantizeFxOps
