irqchip: Make irq-msi-lib.h globally available

JIRA: https://issues.redhat.com/browse/RHEL-120705

    irqchip: Make irq-msi-lib.h globally available

    Move irq-msi-lib.h into include/linux/irqchip, making it available
    to compilation units outside of drivers/irqchip.

    This requires some churn in drivers to fetch it from the new location,
    generated using this script:

            git grep -l -w \"irq-msi-lib.h\" | \
            xargs sed -i -e 's:"irq-msi-lib.h":\<linux/irqchip/irq-msi-lib.h\>:'
