The configuration option was deprecated and removed as the default in
MCUBoot commit 9315654d7951fb2c269251db94e04cd062d0b89a.

Add a brief subsection about how to build a Zephyr application without
flashing it.

The sysbuild documentation refers to CMakeLists.txt which can lead the
user to believe this call can be added to the <sample>/CMakeLists.txt
file.
This file is sourced as part of the Zephyr CMake build and not sysbuild
CMake build.
Therefore change the description to sysbuild.cmake.

This commit introduces the possibility of a sample to locate
configuration files for extra images that are used when building with
MCUboot.
This allows use-cases where a sample, A, want to include MCUboot but has
adjustments to the default MCUboot configuration.
By adding a Kconfig fragment `<sample>/sysbuild/mcuboot.conf`, then that
fragment will be used together with the default configuration for
MCUboot.
It is also possible to completely replace the MCUboot configuration.
This is done by creating `<sample>/sysbuild/mcuboot/` folder.
This folder will then be used as the `APPLICATION_CONFIG_DIR` when
building MCUboot.

The examples showing how to include an extra Zephyr project into the
build wrongly used `BUILD_ALWAYS True`.
The `ExternalZephyrProject_Add()` already adds this flag implicit to
ensure Zephyr based projects are always built correctly.
Thus remove the flag in the doc example as it is wrong and causes CMake
error if users tries to pass on this flag.

This is this initial sysbuild guide on what sysbuild is and how to build
a sample using sysbuild.
It provides an architectural overview of sysbuild.
Descriptions on how to use `west build` or `cmake` + `ninja` to build
projects with the sysbuild infrastructure.
Flashing is described through the use of `west flash`.
Extending sysbuild with additional Zephyr based applications are
described, and reference to CMake documentation for including non-Zephyr
based applications are provided.
