For the specified board, in the specified destination directory,

files should be compatible with the pre-hwid-tool era code.
The goal of this command is to enable maintaining data in the new
format for use with factory branches that can only consume the older
The 'extra' argument can specify a file that contains extra dict
extries that will be included in each of the hwid files. This is
useful for specifying the legacy fields that no longer exist in the
new data format.
This command will be removed once we are no longer supporting any
boards that depend on the old-style data formatting.
