This works by overwriting z_isr_install()'s definition (possible since the symbol is now weak) with our own definiton. Whenever trying to register a new ISR/arg pair, z_isr_install() will check to see if the interrupt line is already in use. If it's not then it will not share the interrupt and will work exactly as the old z_isr_install(), meaning it will just write the new ISR/arg pair to _sw_isr_table. If the interrupt line is already being used by an ISR/arg pair then that line will become shared, meaning we'll overwrite _sw_isr_table with our own (z_shared_isr, z_shared_sw_isr_table[irq]) pair.
