Instead of finding the address of the spurious irq function in the
intList section we now rely on the linker to find the address in the
_irq_spurious symbol.
This is a migration from using code generation to using the C language
which we in the general case we should aways strive towards.
In this specific case it makes the generated code 'irq_tables.c'
easier to read as we replace magic numbers with the &_irq_spurious
token.
Also, the path through the build system that _irq_spurious makes is
much shorter, so it is much easier for a user to understand how it is
used.

This patch adds USB descriptor and data section macros.
Use USBD_DESCR_..._DEFINE macros to place the parts of USB device
descriptor in predetermined order in the USB descriptor
section. The parts of a device descriptor are also
sorted according to the macro argument. All parts of a
particular device descriptor must use the same argument.
Use USBD_CFG_DATA_DEFINE macro to place the data struct

This patch adds a RAM section for the USB descriptors and
USB interfaces data.
The parts of USB descriptor can be declared independently in
different USB class drivers or functions. These must then be
placed in a predefined order one after the other without gaps
in a RAM section. There may also be several device descriptors
in the section such as for USB DFU.
Since at runtime the number of interfaces and endpoints in the
composite device descriptor is unknown, they must be corrected.
The class drivers or functions use the usb_cfg_data struct to
store the callbacks, interface and endpoints data. This struct
must also be corrected and needs to be placed in the data section.
The descriptor section and data section must be processed by
the USB Device Stack before the enumeration.

The _THREAD_POLLING bit in thread_state was never actually a
legitimate thread "state". It is a clever synchronization trick
introduced to allow the thread to release the irq_lock while looping
over the input event array without dropping events.
Instead, make that flag a word in the "poller" struct that lives on
the stack of the thread calling k_poll. The disadvantage is the 4
bytes of thread space needed. Advantages:
+ Cleaner API, it's now internal to poll instead of being globally
visible.
+ The thread_state bit space is just one byte, and was almost full
already.
+ Smaller code to write/test a full word and not a bitfield
+ Words are atomic, so no need for one of irq lock/unlock pairs.

The original implementation of CONFIG_THREAD_MONITOR would
try to leverage a thread's initial stack layout to provide
the entry function with arguments for any given thread.
This is problematic:
- Some arches do not have a initial stack layout suitable for
this
- Some arches never enabled this at all (riscv32, nios2)
- Some arches did not enable this properly
- Dropping to user mode would erase or provide incorrect
information.
Just spend a few extra bytes to store this stuff directly
in the k_thread struct and get rid of all the arch-specific
code for this.

The adv_send() function was incorrectly decoding the 5-bit value (it
was using it directly as milliseconds), which effectively lead to the
code always picking the controller's minimum supported interval.
Fix this issue, but do it by simplifying the (re)transmission state
tracking so that the state is always stored in the original "packed"
8-bit value, where 5 bits are reserved for the interval, and 3 for the
count.

k_work_init() was not initializing all fields in the k_work struct.
Mainly, the atomic_clear_bit() function call was reading a possibly
uninitialized value, clearing a bit, and assigning it back to the
`flags` member. The `_reserved` member was never initialized.
With the struct now initialized with the _K_WORK_INITIALIZER() macro,
initialization is consistent regardless of how a `struct k_work` is
initialized.
This fixes the Valgrind issues found in #7478.

The logic for using _Static_assert() was a little broken. We were
using it when on GCC 4.6+ AND when __STDC_VERSION__ said we were on
C99 or better. But it's not a C99 feature, it's a C11 feature. And
if GCC provides it as an extension, that's unrelated to a particular
language version. This should have been "GCC 4.6+ OR C11+".
This actually broke on the ESP-32 IDF toolchain, where (when using
-std=c99) the compiler was actually defining a C99 macro instead of
the C11 one, and choosing to use the wrong (and independently broken)
handling incorrectly. Fixes#8093.
