Print implementation-only imports in the private textual interface only if also importing SPI. This allows to export types from implementation-only imports in SPI and brings the private textual interfaces in line with the binary interfaces. This is a temporary solution as we need to better design the language feature around this. This feature requires passing -experimental-spi-imports to the frontend that generates the private swiftinterface file.
