This change adds an additional (optional) section to the .yaml file which can enumerate the names of the locales. If present, these names will be appended to the end of the bmpblock and the (new) locale_string_offset field in the BmpBlockHeader will point to it. The names are encoded as a series of null-terminated ASCII strings. The end of the series is indicated by an extra null (for example, "en_US\0fr\0\0" names two locales). The BIOS does not use this information. Factory or OOBE could use it to select the initiale locale for the BIOS screens from the list of locales included in the BmpBlock.
