Remove address-of operator ('&') when assigning `init_fn`
function pointer in `DEVICE_DT_INST_DEFINE` macro.
This change aims to maintain consistency among the drivers in
`drivers/serial`, ensuring that all function pointer assignments
follow the same pattern.

The existing configuration of the ESP32 UART FIFO thresholds
was fixed, leading to inefficiencies in handling
Modbus RTU packages exceeding this size.
This commit introduces two new Kconfig options,
allowing users to adjust the esp32 fifo thresholds as needed.

After enabling interrupts, serial_esp32_usb_irq_tx_enable() calls the
interrupt handler to handle any old events that occurred while interrupts
were disabled. However, this happens in the callers context, so if an
interrupt arrives during the call, it will call the interrupt handler again
resulting in corruption if the interrupt handler is not reentrant.

When low power mode is enabled then whenever UARTE is not active,
driver attempts to put the peripheral into the lowest power state
by stopping and disabling UARTE. However, it did not put pins into
sleep state which could lead to increased current consumption.
Adding pins state handling to the low power mode.
Pins are put into sleep state only if CONFIG_PM_DEVICE=y.

Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
Most of the changes here are scripted, check the PR for more
info.

Two Kconfig symbols were tied to a board-specific DT nodelabel - namely
the `NRFX_UARTE_CONFIG_RX_CACHE_ENABLED` and `UART_<n>_RX_CACHE_SIZE`
were tied to `shared_ram3x_region` - but this is not necessary.
That DT node is where the UARTE driver RX/TX cache buffers are placed
in the default nRF54H20 DK memory map, but on another board, they could
be located somewhere else.
The exact memory sub-regions used for this purpose are indicated using
the `memory-regions` property on each UARTE instance, which should be
generic enough already, so let's use that instead.

This change allows to use DTR line driven from external serial port
that when active (low) will prevent UART device from going to sleep.
It will also wake up platform when DTR line becomes active.
DTR line is often activated in serial port connected to host computer
when operating system opens serial device like COMx for Windows
or /dev/ttyACMx /dev/ttyUSBx for Linux based systems.
DTR line (specified in device tree) will be used by WAKEUP and PDC
controllers (via GPIO driver) to handle DTR line changes.
