LayerManager: avoid side effects on exports that do not include proxyShapes.#4553

… shapes Before this change, prepareForExportCheck() always called prepareForWriteCheck(), regardless of the export mode. This caused export operations such as Export Edits to still run the LayerManager write path. That could raise unnecessary save dialogs and unnecessarily serialize anonymous session layers, so a later proxyShape recompute could recreate them as different anonymous layers with different identifiers and trigger stage recomposition.

Before this change, prepareForExportCheck() always called prepareForWriteCheck(), regardless of the export mode.
As a result, export operations such as exporting reference edits to editMA files still ran the LayerManager write path even though no LayerManager data needed to be persisted. This could raise unnecessary maya-usd save dialogs and trigger unnecessary session layer serialization, which could later lead to avoidable stage recomposition when a proxyShape is recomputed.
