x86/vector: Untangle internal state from irq_cfg
The vector management state is not required to live in irq_cfg. irq_cfg is
only relevant for the depending irq domains (IOAPIC, DMAR, MSI ...).
The seperation of the vector management status allows to direct a shut down
interrupt to a special shutdown vector w/o confusing the internal state of
the vector management.
Preparatory change for the rework of managed interrupts and the global
vector reservation scheme.
