The bits allocated for each aggregator level only need to be enough to
encode CONFIG_MAX_IRQ_PER_AGGREGATOR, instead of the combined number of
IRQs from all aggregators in that level.
Add additional check for L3 interrupts as well, if it is enabled.
Updated the assert in `z_get_sw_isr_table_idx()` to be more verbose.
