[MAYA-126188] Saving the file discards usd selection

**Describe the bug**
When using File->Save As or File->Save, it discards the USD selection.

If a native maya node is selected, it maintains this selection.

**Steps to reproduce**
Steps to reproduce the behavior:
1. Open `Kitchen_Set`
2. Navigate to Create -> Polygon Primitives -> Sphere
3. Select `|Kitchen_set|Kitchen_setShape,/Kitchen_set/Arch_grp/Kitchen_1`
4. Translate the `Kitchen_1` (make an edit that needs to be saved)
5. Select `Kitchen_1` and `pSphere1`
6. Navigate to File->Save (follow the prompts if needed)

Notice that the `Kitchen_1` is no longer selected. However, saving maintains the native maya selection.

**Expected behavior**
We would expect the same behaviour as native maya nodes where the selection is maintained when saving.
