[Enhancement]: Sparse index support for mmap

[elstic]

Is there an existing issue for this?

• I have searched the existing issues

What would you like to be added?

Please support the index of sparse for mmap.

Why is this needed?

You cannot use a sparse index with mmap.

Anything else?

Adding mmap support for sparse index should be done in knowhere, not Milvus. We need mmap for sparse raw data in Milvus.

Both are included in GA todo items, which I'll share more details next week. This is not part of 2.4.0.

Also I will track all GA items for sparse vector in #29419, including mmap, please close this if you don't mind @elstic
