MISRA Rule 5.7 requires uniqueness of tag identifiers. Shell is
frequently problematic because many code uses `const struct shell
*shell`. This causes CI noise every time one of these shell files is
edited, so let's update all of them with `const struct shell *sh`
instead.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

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

If the shell root command shall be set in the application, e.g. for
implementing a login scheme, it is an advantage to set this already
during shell init.
This is now implemented using a new Kconfig variable SHELL_CMD_ROOT.

Function shell_root_cmd_find was only used in shell_utils.c file.
Hence it is changed to static and renamed to root_cmd_find.

Default values were fixed in the code. Moved to Kconfig to allow
customized configuration. Custom configuration may be used to prevent
line breaking injected on terminal width.

Added special flag that can be used to indicate that optional
arguments are passed without any parsing (e.g. quotation marks
removal). Modified execute command to parse command line buffer
argument by argument.
After this change it is possible to forward whole command to
command handler (using select).

The "select" command has been implemented, which allows user to
narrow down the command tree.
This implementation differs from the "select" command available
in the legacy shell. In a new implementation, if the selected
command has a handler and if the user has not entered the
registered subcommand, the shell will call the handler of selected
command and pass the text as arguments.
This may be useful, for example, if someone wants to use the
shell as an interface to a modem that supports AT commands.
Instead of each time you write e.g:
at at+command1
at at+command2
at at+command3
user can execute following commands:
select at
at+command1
at+command2
at+command3
where:
at - root command for passing at commands to the modem
at+commandX - at command passed to the modem.

This change removes special handling for shell root commands.
Currently there is one loop in execute function that is used
to search commands on each level.
Fixed a bug where command buffer has been processed twice
when it was not needed (wildcards not found).
This change will allow to simplify "select" command
introduction.

Everywhere the return of this function was being assigned to u16_t to
save space on stack. Instead of casting in all these places (and may
end up with overflow), just changing this function's return.
Note that the function itself is not checking for overflow yet since
I'm not sure this can happen and/or is a problem. Though now we have
only one single point to fix this problem.

Added static functions for setting and getting shell
internal flags.

shell parses output string and it adds \r for each found \n.
It is no longer needed to keep \r for each shell message.

2. Simplified command handlers with new shell print macros.
3. Removed help functions from command handlers.

New shell support features like:
- multi-instance
- command tree
- static and dynamic commands
- multiline
- help print function
- smart tab (autocompletion)
- meta-keys
- history, wildcards etc.
- generic transport (initially, uart present)
