enhance: calculate the accuracy memory usage while loading segment (#30473)

[yah01]

the old version Knowhere would copy the index data while loading, we need to consider this to avoid OOM.

Knowhere provides a util function to indicate whether it will load the index with disk, if not, we need to double the memory usage prediction for index data
