The shell name defined with `SHELL_DEFINE` is implicitly
guaranteed to be unique while it is possible that more than one
shell backends can have the same prompt.
Print the name of the shell backend alongside with its prompt
to differentiate between the backends.

Until now iterable sections APIs have been part of the toolchain
(common) headers. They are not strictly related to a toolchain, they
just rely on linker providing support for sections. Most files relied on
indirect includes to access the API, now, it is included as needed.

This change to the shell API enables the user to retrieve the
return code of the most recently run shell command. This is
useful both for users wanting specific information beyond the print
statements in a command, but especially for automated users
that prefer a simple return code to parsing human readable text.
This was tested using all default shell commands, as well as
eeprom, flash, and i2c, where specific errors could be forced.
In all cases, the correct return value was returned by the new
retval command.

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.

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.

Removing help "options" from shell API.
Currently SHELL_OPT macro is not used by users. What is more
commit: a89690d10f ignores possible options created in
command handler by the user. As a result they are not printed
in help message.
Second, currntly implemented "options" in command handlers options are
implemented without SHELL_OPT macro.
And last but not least this change will allow to implement
help handler in a way that user will not need to think about calling
functions printing help in a command handler.
