Should not compile successfully when there are multi provides in module-info for the same spi.

[Meodinger]

To reproduce the issue, just use <moduleInfoSource> or <moduleInfoFile> for input, and provide impls for the same SPI twice like

module test {
    provides some.module.spi with test.impl.provider1;
    provides some.module.spi with test.impl.provider2;

    // The correct format is
    // provides some.module.spi with 
    //         test.impl.provider1,
    //         test.impl.provider2;
}

This module-info file should not be compiled successfully but it does.
