    drm/xe/gsc: add support for GSC proxy interrupt
    
    The GSC notifies us of a proxy request via the HECI2 interrupt. The
    interrupt must be enabled both in the HECI layer and in our usual gt irq
    programming; for the latter, the interrupt is enabled via the same enable
    register as the GSC CS, but it does have its own mask register. When the
    interrupt is received, we also need to de-assert it in both layers.
    
    The handling of the proxy request is deferred to the same worker that we
    use for GSC load. New flags have been added to distinguish between the
    init case and the proxy interrupt.
