Shell log backend was using k_fifo to enqueue log messages.
It was using field in log message that was used for same
purpose in log_core before passing message to backends.
However, this method supported only single shell as
other shell was corruption the fifo because field was
reused.
Modified shell log backend to use k_msgq for pending
messages.

Currently shell UART backend is interrupt driven if UART driver
is interrupt driven. That can be limitation if one instance
wants to use interrupts but shell UART should not.
Added option to shell uart to be able to control use of
interrupts. By default interrupts are enabled if driver
supports it.

RTT backend was returning number of transfered data equal
to requested amount because it was not taking into
account value returned by SEGGER_RTT_Write. As the outcome
data could be lost.

k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.

Shell log backend was enabled too early, before shell thread was
up and running. That could lead to failure if log thread passes
log message to shell log backend.
Additionally, modified algorithm for multiplexing log output with
shell prompt. In case of logs flood prompt was unreadable because
it was deleted immediately after being printed. Added k_sleep
after printing prompt if any character was typed. This ensures that
shell prompt is readable if user uses it.

Added dummy backend which can be enabled with Kconfig. By default it is
disabled because it needs the same amount of memory as other phisical
backends. It shall be use only for commands testing purposes.

1. Changed return value of function: shell_cmd_precheck from bool to
int. Now it returns:
0 when argument count is correct and help print is not requested
1 when help was requested and printed
-EINVAL on wrong arguments count
This change simply shell_cmd_precheck usege in command handlers.
2. Unified all commands in shell_cmd.c file.
3. Fixed a bug where help was not printed on wrong argument count.

Some terminals literally interprets shell output data. Hence to print
a message in new line shell needs to send `\r\n` each time. To minimize
flash usage user can now send `\n` as a line delimiter and shell will
automatically add missing CR character.
