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.

By default, kernel event logger is using the system timer. But on
some platforms where the timer driver maintains the system timer
cycle accumulator in software, such as ones using the LOAPIC timer,
the system timer behavior leads to timestamp errors. For example,
the timer interrupt is logged with a wrong timestamp since the HW
timer value has been reset (periodic mode) but accumulated value not
updated yet (done later in the ISR).
This patch is adding the possibility to register a timer callback
function that will be used by the kernel event logger. For example,
on Quark SE, this allows using RTC or AON counter which accuracy is
sufficient and behavior more straight forward compared to system
timer.

OS tick period (usually 10 ms) is not sufficiently precise for task
execution analysis (like processing CPU load per context)
With that modification, the timestamp used by the kernel event logger
is 32-bit LSB of platform HW timer (for example Lakemont APIC timer
for Quark SE).
This timer period is very small and leads to timestamp wraparound
happening quite often (e.g. every 134s for Quark SE).
This wraparound must be considered when analyzing kernel event logger
data and care must be taken when tickless idle is enabled and sleep
duration can exceed maximum HW timer value.

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 is being removed for a few reasons:
- AFAICT this is the only API in Zephyr that follows an allocate/free
model.
- There are no public APIs in the interrupt subsystem for releasing
or reconfiguring an interrupt. This code was relying on arch-specific
private APIs. If we really want to keep this capability we should
make these APIs public and consistent across arches.
- The use-case for this API is not clear, as Zephyr is not intended
for hot-pluggable peripherals. Built-in hardware tends to need its
interrupt for its entire life cycle.
- The current implementation of dynamic interrupts on x86 does not
support freeing a dynamic IRQ that was reserved with
irq_connect_dynamic(), causing this code not to work. To add this
would require reimplementing _get_dynamic_stub() to use a bitfield
or set of bitfields to track unused stubs rather than the simple
counter it uses now.

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.

Simplifies the nanokernel timer API so that the timeout parameter must be
specified when invoking nano_isr_timer_test(), nano_fiber_timer_test(),
nano_task_timer_test() and nano_timer_test().
This obsoletes the following APIs:
nano_fiber_timer_wait()
nano_task_timer_wait()
nano_timer_wait()
Note that even the though the new API requires that the timeout parameter
be specified, there are currentl only two acceptable values:
TICKS_NONE and TICKS_UNLIMITED
Theoretically, the current implementation would allow one to supply a
finite positive value for the timeout and the system would wait up to
that many ticks for the timer to expire. However, it is thought that
that unnecessarily complicates the nanokernel timer model and so it is
left as an unsupported option. Should that change, then that feature
could be enabled by updating the documentation.

Changes the task IRQ API so that not only does task_irq_test() become
task_irq_wait(), but that the timeout parameter must also be specified.
Use of task_irq_wait() obsoletes the following APIs:
task_irq_test()
task_irq_test_wait()
task_irq_test_wait_timeout()
_task_irq_test()

Introduce the device_sync_call_t object type and its API.
This object type allows one thread to perform synchronous calls into a
driver. Only one thread can do such calls per instance of the
device_sync_call_t object since it makes a global record of what type of
thread is waiting on it.
Based on an idea from Dmitriy Korovkin and Peter Mitsis, moving their
proposal to a more generic API provides the solution for all device
drivers that exposes synchronous API in an interrupt based
implementation.

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.

Standardizes appearance, corrects errors, improves readability,
and fils in gaps. Also relocates documentation for internal APIs.
Removes mention of non-existent task_sem_group_take() API from
the Kernel Primer document. The microkernel's semaphore group logic
currently allows a task to take a semaphore from a semaphore group
in a blocking manner.
