core: arm: virt-aware FF-A thread_foreign_intr_exit()

thread_foreign_intr_exit() is called after the thread state has been
saved and the thread is suspended. With virtualization enabled
(CFG_NS_VIRTUALIZATION=y) the virt_unset_guest() is also called. After
this, the guests thread contexts aren't available any longer. For FF-A
thread_foreign_intr_exit() needs a few fields from the suspend threads
context so extract those before suspending the thread and pass them as
parameters for thread_foreign_intr_exit().

core: arm: boot: enable native interrupts before initcalls

Enable native interrupts on Arm architectures when executing
initcalls (early,service,driver,final). This change allows drivers
to leverage interrupts during OP-TEE core initialization, as for example
detecting a firewall access violation when it occurs. Before this change,
OP-TEE needed to complete its initialization and return the secure
monitor for secure interrupts to be handled.

Note that when CFG_NS_VIRTUALIZATION is enabled, initcalls called from
virt_on_stdcall() is not changed here since they are executing from a
standard call entry hence with native and foreign interrupts already
default unmasked.

This change fixes an issue when using interrupt_dt_get_by_index()
