Move setIRQTrigger from <arch>/hardware.h into interrupt.h together
with the rest of the IRQ interface, because it is now a visible
interface even for platforms and architectures that do not provide the
functionality.

Separate priority drop from deactivation so that when the kernel
delegates interrupts to userlevel, they can be left in the active state
until user level performs the ack invocation which deactivates them.
This is more efficient than doing a disable and enable operation
for each handled interrupt as it is core local and doesn't require
sending operations to the GIC distributor..

All the kernel header files now use pargma once rather than the ifndef,
as the pre-processed C files do not change while header files
are protected with pargma once. This will also solve any naming issues
caused by ifndef.
This commit also converts our own copyright headers to directly use
SPDX, but leaves all other copyright header intact, only adding the
SPDX ident. As far as possible this commit also merges multiple
Data61 copyright statements/headers into one for consistency.
Explicitly create a struct definition for irq_t on SMP Arm
configurations. This makes it a lot harder to mistakenly use the wrong
irq encoding when moving an irq between a cnode index and hardware irq
number / core. A couple areas where this was being handled incorrectly
was fixed as part of the refactor. When performing an ipi for masking
PPI interrupts, the idx encoding is used as it fits into a single word.
Every platform has to implement a standard set of interrupt interfaces
that the kernel uses to interract with a machine's interrupt controller.
Providing a single header file for each of these functions provides a
single location to document their behavior.
