Subject: [PATCH] fix: Allow to compile on windows (#41617)

This PR fixes https://github.com/milvus-io/milvus/issues/41384 on 2.5.

Related to #41448.

When using milvus client and compile on windows, the compilation failed
with the undefined RSS error.

On windows, the way to get memory used is the same as on darwin.
