The Adafruit ItsyBitsy M4 express is a small (36 mm x 18 mm) ARM
development board with an onboard RGB LED, USB port, 2 MiB of SPI
flash, and range of I/O broken out onto 23 GPIO pins.

This test was configuring the system tick period to 1 second.
The test also constantly aligns to system tick boundaries,
in between each test part, which means the test runs for very long
(it is holding for longer than 1 minute just on those waits between
tests alone).
The nrf sys tick driver configures the RTC to produce still
all RTC interrupts at 32KHz intervals, which cause lots of
interrupts which slow down simulation quite bit.
Overall the test could take longer than 30 seconds in the
nrf52_bsim in CI even that this platform simulated time is decoupled
from real time.
=> Add a new config overlay for the nrf52_bsim board so
we configure there a much higher system tick frequency
It does not affect the test in any way more than shortening
the wait periods between in test part.
Also increment the sys tick to twice per second to speed up
the test in other platforms.

As the int types defined in include/zephyr/types.h are typdef's we
utilize a Kconfig option (LEGACY_ZEPHYR_INT_TYPES) to enable/disable
the support for them. By default to LEGACY_ZEPHYR_INT_TYPES not
being enabled and add an explicit test to ensure the types continue to
function until removed in the future.

Move to using PRIu64/PRId64 instead of %llu/%lld since on
native_posix_64 the uint64_t/int64_t type is defined in terms of 'long

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.

When `z_get_fd_obj_and_vtable()` function returns NULL (no valid entry
in the FD table for the socket), there is no need for further usermode
checks on the `ctx` pointer, as there is nothing to invalidate in that
case.

This test sets a timer using one clock, waits using a second clock,
then sees whether the remaining time is the expected value. When the
two clocks are skewed the comparison requires a threshold. Provide a
means to estimate the maximum expected error.

Some ticks are counted additionally when the autoreload
interrupts were too close together.
This patch improve the counts of the clock cycle.
lptim_fired worked badly in particular because the flag ARRM
was not raised when the interrupt was forced.

The original sockets system calls used file descriptors which
were actually net_context pointers. For all socket system calls,
any calls from user mode would check if the caller had permission
to use the net context.
This was later changed to not stuff net_context pointers into file
descriptors, but all the permission checking was unintentionally
lost, allowing all threads on the system to
read/write all socket file descriptors in the system at will, with
no way to isolate applications running on the same microcontroller
from each other's network activity.
This patch restores the permission checks on network context objects
for socket system calls that originated from user mode.
The call to z_object_recycle() was never removed from
zsock_socket_internal(); this is again leveraged to grant the
caller who opened the socket permission on the net_context
associated with the returned file descriptor.
To ensure that all socket calls do this checking, all uses of
z_get_fd_obj_and_vtable() have been routed through get_sock_vtable().
Objects have initialization state set and thread permissions
reset to just the caller in common zsock_socket() code.

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().
Checking for valid object type enumeration values moved
completely to the implementation function.
A few debug messages and comments were improved.
Futexes and sys_mutexes are now properly excluded from
dynamic generation.
