acrn-config: add a script to generate config sources from XMLs

In order for a unified interface for generating configuration sources from
board and scenario XMLs, this patch introduces a script named genconf.sh
which takes XML files as inputs and generate sources under the specified
directory. Once used in Makefiles, this script helps to minimize the
impacts on the Makefiles when we refine the configuration source generation
process in the future.

This patch also adds a non-zero return value to board_cfg_gen.py and
scenario_cfg_gen.py so that we do not need to inspect the logs to determine
if the generation succeeds.
