zephyr: support shared PD interrupts
Some boards share an interrupt line between multiple PD ports by running
pd_shared_alert_task in a task instead of individual per-port tasks.
Add support for that by adding USB-C options for shared interrupts and
using those to enable the shared interrupt task for the chosen ports.
