Add public APIs for PCIe endpoint driver:
- EP configuration space read/write
- Mapping/Unmapping of Host buffer and PCIe outbound region
- Raise interrupt to Host
These are minimal base APIs to make PCIe EP functional.
Also, add a Kconfig and an empty CMakeLists.txt for drivers to extend.

mqtt_utf8 structure is used to store the client_id, user_name, password,
topic, will_message.
There is no reason for the mqtt code to modify such data, therefore we
can constify the utf8 pointer.
This would also means that theses client, topic, ... strings can be
safely stored in ROM.

This was added because GNU G++ doesn't support the built-in function
used to produce a compile-time error when invalid parameters are
passed to the macro imlementation. The template implementation does
not work on declarations like this:
mytype array[] = { ... }
because it requires an explicit size for the template parameter.
Remove the template specialization, and support C++ with a version of
the macro that doesn't involve references to undefined builtins.

As written the specification when both period and pulse are zero is
inconsistent: allowed behavior would be to drive the pin at constant
active or constant inactive, depending on which condition was checked
first.
Clarify that driving constant active level requres a non-zero pulse

As the int types defined in include/zephyr/types.h are typdef's we

On 64-bit arch's like AARCH64, x86_64, or riscv-64 the way {u}int64_t
will differ from how its defined on 32-bit arch's. Do the same trick we
do for {u}int32_t for {u}int64_t so that the type is the same regardless
of what we are building for.
This keeps things like %lld working the same regardless of 32-bit or
64-bit arch.

We now have a low-level function z_dynamic_object_create()
which is not a system call and is used for installing
kernel objects that are not supported by k_object_alloc().

A few debug messages and comments were improved.

Certain types of system call validation may need to be pushed
deeper in the implementation and not performed in the verification
function. If such checks are only pertinent when the caller was
from user mode, we need an API to detect this situation.
This is implemented by having thread->syscall_frame be non-NULL
only while a user system call is in progress. The template for the
system call marshalling functions is changed to clear this value
on exit.
A test is added to prove that this works.

Adjusting the input value to allow round to nearest can cause an
overflow which invalidates the expectation that the 32-bit result is
the low 32 bits of the 64-bit result. If the adjustment overflows do
the full-precision conversion and truncate in the caller.

The k_queue data structure, when CONFIG_POLL was enabled, would
inexplicably use k_poll() as its blocking mechanism instead of the
original wait_q/pend() code. This was actually racy, see commit
b173e4353f. The code was structured as a condition variable: using
a spinlock around the queue data before deciding to block. But unlike
pend_current_thread(), k_poll() cannot atomically release a lock.
A workaround had been in place for this, and then accidentally
reverted (both by me!) because the code looked "wrong".
This is just fragile, there's no reason to have two implementations of
k_queue_get(). Remove.
Note that this also removes a test case in the work_queue test where
(when CONFIG_POLL was enabled, but not otherwise) it was checking for
the ability to immediately cancel a delayed work item that was
submitted with a timeout of K_NO_WAIT (i.e. "queue it immediately").
This DOES NOT work with the origina/non-poll queue backend, and has
never been a documented behavior of k_delayed_work_submit_to_queue()
under any circumstances. I don't know why we were testing this.

The implementation of Z_TIMEOUT_US() and Z_TIMEOUT_NS() in the legacy
timeout API is incorrect in that it multiplies the input value by the
scale factor rather than dividing it, making K_USEC(3) equivalent to
K_SECONDS(3). Replace with implementation that doesn't surprise a
user that happens to find and use them.
