drivers: interrupt_controller: changes in shared irq

Updated the shared IRQ handler function in the shared interrupt controller
drivers to include support for the 'irq_number' parameter. When a single
driver manages multiple shared IRQs, it becomes challenging to determine
which IRQ line is invoking the handler. Therefore, I've introduced an
option to share the IRQ number to address this issue.
