First, the API ops are available only if
CONFIG_UART_USE_RUNTIME_CONFIGURE=y, but the driver was not guarding the
code. Also, according to the API specs, these functions are optional,
and the interface already returns -ENOSYS if they are not implemented.
To solve both problems, just drop the dummy implementation.

When device runtime pm is enabled on console device, do not suspend
device synchronously on each char transmission, but rather use asynchronous
suspension request.
This will save useless and costly suspension/resumption procedure, which
can involve uart device clock suspension but also pin configuration
to sleep state (which itself involves gpio clock activation ...).
On STM32, using asynch device suspension allows to divide by 3 the
transmission time of a character chain.

Receiving uart messages like: "\r*\n*\n" ('*' is a wildcard here) resulted
in invalid echo and invalid console_getline() output.
For example after receiving "\rabc\nd\n" uart_console_isr() echoes
"\r\nabcd\r\n" (note that "\r\n" before 'd' is missing) and after calling
console_getline() twice we received "" and "abcd".
uart_console_isr() changes single occurences of '\n' and '\r' to "\r\n" and
to avoid outputting "\r\n\r\n" after receiving "\r\n" it keeps track of the
last character. But it was tracking only the control characters not all
characters so in case of inputs like "\r*\n" the '\n' was omitted because
the last tracked character was '\r'.
Its fixed by tracking last character no matter of its type

When using console debug server hooks, not all characters are
processed if the server hook returns non-zero for one character
while there are other characters in the buffer. This is seen
when using a fast console (like USB) where multiple characters
come in before the ISR is called. Fix it by continuing to
process characters instead of returning from the ISR with
characters still in the buffer.

Previously, the `uart_console_isr()` routine assumed that the
return value of several uart API functions would only ever
return the equivalent of a boolean value. In fact, an integer
is returned on occasion, and that integer can take on many
values.
Since unary operations would either go to "true" or "false"
and since any non-zero integer evaluates to "true", even a
return value of something like `-ENODEV` would evalueate
to true.
Explicitly compare against the integer-equivalent value of
the expected boolean output.
With this, in the case of errors, negative return values do
not evaluate to "true", and the infinite loop is avoied.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.

All posix arch boards are required to provide the same

So, instead of having a different driver for native_posix and the
bsim boards, let's have a common one which uses this API.
This in turn results in the printk strings being printed in
the same underlaying backend as before with individual drivers.
A part from this, the native_posix console driver was a full
backend for the now long gone Zephyr console shell
(named legacy_shell from 527256501f

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Allow the uart_console console_out implementation to integrate with
'Device Runtime Power Management'.
Without using runtime PM, it is impossible for the application to manage
the power state of a UART instance, given that any module in the
application could theoretically LOG_* or printk at any point in time.
This removes the need to manually call `pm_device_state_set` when the
lowest power states must be reached, while still allowing console and
printk messages to be output.

The `ARCH` init level was added to solve a specific problem, call init
code (SYS_INIT/devices) before `z_cstart` in the `intel_adsp` platform.
The documentation claims it runs before `z_cstart`, but this is only
true if the SoC/arch takes care of calling:
```c
z_sys_init_run_level(_SYS_INIT_LEVEL_ARCH);
```
Which is only true for `intel_adsp` nowadays. So in practice, we now
have a platform specific init level. This patch proposes to do things in
a slightly different way. First, level name is renamed to `EARLY`, to
emphasize it runs in the early stage of the boot process. Then, it is
handled by the Kernel (inside `z_cstart()` before calling
`arch_kernel_init()`). This means that any platform can now use this
level. For `intel_adsp`, there should be no changes, other than
`gcov_static_init()` will be called before (I assume this will allow to
obtain coverage for code called in EARLY?).
