Allow the env__dfu_configs boardenv data to specify the set of DFU transfer sizes to test. Manually specifying test sizes is useful if you wish to test multiple DFU configurations (e.g. SD card ext4 filesystem, SD card whole raw partition, RAM, etc.), but don't want to test every single transfer size on each, to avoid bloating the overall time taken by testing. If the boardenv doesn't specify a set of sizes, the built-in list is used as a default, preserving backwards-compatibility.
