o3d.io.read_triangle_mesh_from_bytes

### Checklist

- [x] For Python issues, I have tested with the [latest development wheel](https://www.open3d.org/docs/latest/getting_started.html#development-version-pip).

### Proposed new feature or change

There is an `o3d.io.read_point_cloud_from_bytes`, but no pendant for triangle meshes.

The usecase here is an HTTP server, taking STL files as an input. At the moment one has to write a temporary file, then pass that path to open3d.
