Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).
Automated using:
```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c
```

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Refactors all of the counter drivers to use a shared driver class
initialization priority configuration, CONFIG_COUNTER_INIT_PRIORITY, to
allow configuring counter drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The
exceptions are the maxim_ds3231 and mcp7940n drivers which have a
dependency on a SPI driver and must therefore initialize later than the
default device priority.

Remove support for counter_read and counter_get_max_relative_alarm as
they have been deprecated for at least 2 releases. As part of the
removal of counter_get_max_relative_alarm remove the code in all
counter drivers that implemented the API.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

The driver-specific config_info structure referenced from the device
structure is marked const. Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.
Changes produced by scripts/coccinelle/const_config_info.cocci.
Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.

Introduce a new counter API function for reading the current counter
value (counter_get_value()) and deprecate the former counter_read() in
favor of this.
Update all drivers and calling code to match the new counter API.
The previous counter driver API function for reading the current value
of the counter (counter_read()) did not support indicating whether the
read suceeded. This is fine for counters internal to the SoC where the
read always succeeds but insufficient for external counters (e.g. I2C
or SPI slaves).
Fixes#21846.
