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.

Changes the nanokernel stack API so that the timeout parameter must be
specified when invoking nano_isr_stack_pop(), nano_fiber_stack_pop(),
nano_task_stack_pop() and nano_stack_pop().
This obsoletes the following APIs:
nano_fiber_stack_pop_wait()
nano_task_stack_pop_wait()
nano_stack_pop_wait()
Note that even though the new API requires that the timeout parameter
be specified, there are currently only two acceptable values:
TICKS_NONE and TICKS_UNLIMITED
This nanokernel option does not support CONFIG_NANO_TIMEOUTS.
