[PATCH v3 0/5] cmd: add scmi command

[AKASHI Takahiro]

"Scmi" command will be re-introduced per Michal's request.
The functionality is the same as I put it in my patch set of adding
SCMI base protocol support, but made some tweak to make UT, "ut dm
scmi_cmd," more flexible and tolerable when enabling/disabling a specific
SCMI protocol for test purpose.

Each commit may have some change history inherited from the preceding
patch series.

Test
====
The patch series was tested on the following platforms:
* sandbox

Prerequisite:
=============
* This patch series is based on the latest master.

Changes:
========
v3(Nov 14, 2023)
* return -EAGAIN if we want to skip a test.
* use CONFIG_IS_ENABLED() rather than IS_ENABLED().
* remove goto by introducing a function in sandbox implementation.
v2(Nov 13, 2023)
* localize global variables to avoid pytest errors.
