Assert that the `local_irq` of each levels should only ranges
from `0` to `CONFIG_MAX_IRQ_PER_AGGREGATOR`, so that it doesn't
overflow the other aggregators.
Also, assert that the output of `z_get_sw_isr_table_idx` shouldn't
overflow the ISR table.
Update the `sw_isr_table` tests to test the range of
`CONFIG_MAX_IRQ_PER_AGGREGATOR` instead of the entire range of
level bits.

Instead of using a macro guard to prevent functions in
`sw_isr_common.c` from getting compiled when
`CONFIG_DYNAMIC_INTERRUPTS` isn't enabled, do that in
`CMakeLists.txt` instead.

Refactor multi-level IRQ related code from `sw_isr_common.c` to
`multilevel_irq.c` to simplify `sw_isr_common` & macrologies.

Change the internal function to `get_parent_entry`, which
returns the entire entry of table.
Store the parent interrupt controller device in the
`irq_parent_offset` table, and added 2 helper functions to:
1. determine the parent interrupt controller based on the IRQ
2. determine the IRQ of the parent interrupt controller
Declare the `struct _irq_parent_entry` in the header and added
`-` suffix to the struct so that it can be used to test the
functions in testsuites.

Relocate multi-level interrupts APIs out of `irq.h` into
a new file named `irq_multilevel.h` to provide cleaner
separation between typical irq & multilevel ones.
Added preprocessor versions of `irq_to_level_x` as `IRQ_TO_Lx`.

This works by overwriting z_isr_install()'s definition
(possible since the symbol is now weak) with our own definiton.
Whenever trying to register a new ISR/arg pair, z_isr_install()
will check to see if the interrupt line is already in use. If it's
not then it will not share the interrupt and will work exactly
as the old z_isr_install(), meaning it will just write the new
ISR/arg pair to _sw_isr_table.
If the interrupt line is already being used by an ISR/arg pair
then that line will become shared, meaning we'll overwrite
_sw_isr_table with our own (z_shared_isr, z_shared_sw_isr_table[irq])
pair.

Since the shared IRQ code will also use the same logic to compute
the _sw_isr_table index, move the computing logic to a separate
function: z_get_sw_isr_table_idx(), which can be used by other
modules.

In order to bring consistency in-tree, migrate all arch code to the new

z_isr_install is not suited to handle multi-level interrupt formats.
This update allows z_isr_install to accept irq numbers in zephyr format
and place them in the isr table appropriately.

The current `z_isr_install` implementation asserts that the IRQ to
which the ISR will be installed must be disabled.
This commit disables that assertion for the ARM GIC because the SGI-
type IRQs can never be disabled as per the specifications and this
causes the assertion to fail for them.

Promote the private z_arch_* namespace, which specifies
the interface between the core kernel and the
architecture code, to a new top-level namespace named
arch_*.
This allows our documentation generation to create
online documentation for this set of interfaces,
and this set of interfaces is worth treating in a
more formal way anyway.

It was discovered that the xtensa version of
z_arch_irq_connect_dynamic() was being removed along with the old
xtensa architecture support, because it was never included in the asm2
builds.
But there's no xtensa-specific code in it at all. Architectures that
use the existing sw_isr_table mechanism and don't (or can't, in the
case of xtensa which has fixed interrupt priority) interpret the other
parameters might as well have access to a working generic
implementation.
