tools: moveconfig: support CONFIG_SYS_EXTRA_OPTIONS cleaning
We mostly move config options from board header files to Kconfig, but sometimes config defines come from CONFIG_SYS_EXTRA_OPTIONS. Historically, CONFIG_SYS_EXTRA_OPTIONS originates in boards.cfg, which was used as a central database of configuration prior to the Kconfig conversion. Now, we want to migrate to primary entries in Kconfig rather than option list in CONFIG_SYS_EXTRA_OPTIONS, so it should be helpful to have the tool to cleanup CONFIG_SYS_EXTRA_OPTIONS automatically.
