microkernel: deprecate task IRQs
This mechanism does not add enough value to the kernel to be worth
maintaining it. Drivers that need deferred processing of interrupts
can simply define their own task and have the interrupt handler
release an event that the task waits on.
The API is marked as deprecated and it is removed from unit test
coverage as well as the documentation.

Original link "fiber services" does not exist, so renamed to the one
at the head of "nanokernel_fibers.rst".

The "IDT Security" section was removed since the IDT is now always
in a read-only region; dynamic IRQs have been deprecated and will
be removed from the kernel.

We have not found any use-cases for dynamic IRQs where a static
IRQ did not also suffice. Deprecate so that we can eventually
remove from Zephyr and nontrivially decrease the complexity of
the kernel.

It's not a function and requires all its arguments to be build-time
constants. Make this more obvious to the end user to ease confusion.

Rename them to DEVICE_NAME_GET and DEVICE_GET to fit in the 'device'
namespace.

We can save a great deal of RAM this way, it only needs to be
in RAM if dynamic interrupts are in use.
At some point this config option broke, probably when static
interrupts were introduced into the system.
To induce build (instead of runtime) errors when irq_connect_dynamic()
is used without putting the table in RAM, the dynamic interrupt
functions are now conditionally compiled.

This option misunderstands how XIP works. The IDT is ALWAYS in ROM,
the question is whether crt0 will copy it into RAM or not. You can't
save ROM space in this way.

The interrupt API has been redesigned:
- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
It will be used in situations where the new static irq_connect()
won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
exactly the same way as its dynamic counterpart. The old static irq
macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
generated inline with irq_connect()
ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

Change terminology and use SoC instead of platform. An SoC provides
features and default configurations available with an SoC. A board
implements the SoC and adds more features and IP block specific to the
board to extend the SoC functionality such as sensors and debugging
features.

Removes the 'priority' parameter from the IRQ_CONFIG macro.
This parameter was not used anymore in any architecture.
The priority is handled in the IRQ_CONNECT macro.
The documentation is updated as well.

The tables in the Kernel Primer are changed to lists. Making it easier
to update them. Other minor changes were done to ensure consitency.
The :c: and :cpp: markup has been fixed. When the documentation for a
call exists, then it is linked.

A complete rewrite of the Overview section. The revised text
provides a more logical and comprehensive introduction to the
main concepts and capabilities of Zephyr, without providing
an excessive level of detail. (Those details should be provided
by the remaining sections of the Kernel Primer.)
This rewrite has also resulted in some small changes to the
About Zephyr and other Kernel Primer sections.

Moves the Nanokernel Object documentation to a new Nanokernel Services
section within the Kernel Primer. Labels, cross-references, figures,
headings and filenames were updated to reflect the new structure.
