Jamie McCrae 0711f42e3a sysbuild: Add support for snippets
Adds support for sysbuild loading snippets, these can be included
by using e.g.: cmake ... -DSB_SNIPPET=blah for sysbuild
directly or can be used with an application and sysbuild using
-DSNIPPET. Snippets for sysbuild can use SB_EXTRA_CONF_FILE in the
snippet file to specify an extra Kconfig fragment for sysbuild

# Convert Zephyr roots to absolute paths to be used by sysbuild.
#
# This CMake module will convert all relative paths in existing ROOT lists to
# absolute path relative from APP_DIR.
#
# Optional variables:
# - ARCH_ROOT: CMake list of arch roots containing arch implementations
# - SOC_ROOT: CMake list of SoC roots containing SoC implementations
# - BOARD_ROOT: CMake list of board roots containing board and shield implementations
# - MODULE_EXT_ROOT: CMake list of module external roots containing module glue code
# - SCA_ROOT: CMake list of SCA roots containing static code analysis integration code
#
# If a root is defined it will check the list of paths in the root and convert
# any relative path to absolute path and update the root list.
# If a root is undefined it will still be undefined when this module has loaded.
#
# Converted paths are placed in the CMake cache so that they are propagated
# correctly to image builds.
