[CMAKE] Look for Development.Module instead of Development (#129729)

oraluben · web-flow · commit d990dada86a8 · 2024-07-09T11:17:43.000-07:00
Based on the [cmake issue](https://gitlab.kitware.com/cmake/cmake/-/issues/23716) and [manylinux issue](pypa/manylinux#1347), when building a python module, it should find the `Development.Module` module, not `Development`, which includes `Development.Module` and `Development.Embed`, and will expect the shared python library only. After this PR and before #124613, pytorch could be built with a static libpython (e.g. in manylinux). Cherry-pick of 953c647 into release/2.4
