Introduce new logic to set/release pm_constraint during serial TX
transactions.
First change is to introduce an internal flag and utility functions
to control the set/release constraint balancing per uart device.
This way, whatever the mix of transactions or API calls, we
ensure a single uart device can only do 1 or 0 to the PM state
constraint. Constraint can't then be set more than once, released w/o
having been set or released more than it was set.
The last part of the change reworks the triggers for constraints
set/release operations.
In order not to disturb driver operations, if irq driven mode or PM is
enabled, don't enable TC interrupt handling by default.
Instead, map the pm_constraint setting to the way TC flag is handled
in normal mode of operations (irq driven or async).
As a consequence, in irq driven mode, pm_constraint is set/released on
tx_enable/tx_disable api calls, which gives API user full control
on transaction protection vs low power operations.
Finally, we emulate the same behavior on TX poll transaction, by
enabling TC irq at the start of a stream and disabling TC irq once
stream is completed. This is controlled with a dedicated device flag.

In case LwM2M server or bootstrap server rejected

have no use in the state machine.
Finally, simplify the response code logging to prevent code duplication.

TWIM peripherals cannot perform write transactions from buffers
located in flash. The content of such buffers needs to be copied
to RAM before the actual transfer can be requested.
This commits adds a new property (zephyr,flash-buf-max-size) that
informs the driver how much space in RAM needs to be reserved for
such copying and adds proper handling of buffers located in flash.
This fixes an issue that caused that e.g. the DPS310 sensor driver
did not work on nRF SoCs that only have TWIM, not TWI peripherals.

Issue an error logging message when the i2c_nrfx_twim driver lacks
a concatenation buffer big enough to properly handle a call to
i2c_burst_write() function, to give the user a hint what is wrong.
Also use by default a 16-bytes long concatenation buffer for every
instance of the i2c_nrfx_twim driver. Such value should cover most
of the simple uses of the i2c_burst_write() function, like those
in the stmemsc sensor drivers, and when a longer buffer is needed,
the user will be provided with the above message pointing to the
property that should be adjusted.

It happens that CM7 wakeups CM4, before CM4 goes to sleep.
Thus when CM4 goes to sleep,
there no more wakeup from CM7. And CM4 hangs.
For a simple synchronisation implementation,
CM4 doesn't go to sleep any more,
instead it waits (active wait) for CM7 to take HSEM
(meaning that clock configuration is finished).

This commit updates the Zephyr build system such that it does not
include the `zephyr_stdint.h`, which tries to define Zephyr's own type
system, when compiling for the native POSIX architecture.
The native POSIX architecture compiles with the host toolchain and
headers, and there can be conflicts if we arbitrarily define our own
type system (e.g. mismatch between the types and the specifiers defined
in `inttypes.h`).
Note that this is not meant to be a permanent fix; instead, it is meant
to serve as a temporary workaround until we no longer need to define
our own type system.
For more details, refer to the issue #37718.

The Counter resource in the IPSO Push Button object was incremented
silently by the post write handler of the State resource. This prevented
the resource from being marked as updated, effectively preventing
the engine from sending notifications to observers.
Fix this, by setting the new counter value with `lwm2m_engine_set_u64()`
instead. This will update the resource value, and trigger the engine to
send notifications if needed.
