core: interrupt: add interrupt_create_handler()

Adds interrupt_create_handler() API function in interrupt framework.
The function is to be used with interrupt controls obtained
from the DT with interrupt_dt_get() interrupt_dt_get_by_index() or
interrupt_dt_get_by_name().

The function differs from legacy interrupt_add_handler() in that
this latter always reconfigure the interrupt while new
interrupt_create_handler() function assumes the interrupt was configured
from interrupt_dt_get() or friends.

core: interrupt: registering interrupt providers

Adds interrupt chip framework API functions for an interrupt controller
to register as an interrupt provider in the driver probing sequence
based on device tree. This allows interrupt consumer to be deferred
when a dependent interrupt controller is not yet initialized.

Interrupt controllers register a driver in DT_DRIVER providers list
with: interrupt_register_provider().

Interrupt consumer can get their interrupt through DT data with
interrupt_dt_get(), interrupt_dt_get_by_index() or
interrupt_dt_get_by_name().

This change removes inclusion of interrupt.h from kernel/dt.h as it is
not needed and conflicts with inclusion of kernel/dt.h from
kernel/interrupt.h.

Changes dt_driver API function to reference device reference as
