core: interrupt: itr_chip may not require configure handler

The configure handler in struct itr_ops is not required for interrupt
providers which consumers only use the DT to get and configure their
interrupts (with interrupt_dt_get_by_*() and interrupt_create_handler()).
Therefore change itr_chip_is_valid() to not enforce its support
but add back that constraint for the interrupt main controller.

Add an itr_chip_dt_only_init() helper function for interrupt
controllers which consumers only use the DT to configure their
interrupt, that is such controllers do not need a configure handler.

itr_chip_is_valid() is not called outside interrupt.c where it is
used in itr_chip_init() and itr_chip_dt_only_init() so make it a local
function.

core: arm: refactor boot

Introduce CFG_BOOT_INIT_THREAD_CORE_LOCAL0 to indicate that
thread_core_local[0] is initialized before the boot_init_* functions are
called.

thread_init_core_local_stacks() and thread_init_thread_core_local() are
replaced by a new version of thread_init_thread_core_local() for
CFG_BOOT_INIT_THREAD_CORE_LOCAL0=y.

Move initialization of thread_core_local[] from very early to
boot_init_primary_late() where various DTBs containing run-time
configuration are available. This will be needed in later patches when
the number of configured cores can be read from DT or some other
run-time configuration.

Move the "OP-TEE version" print and following code from
boot_init_primary_late() to boot_init_primary_final()
