Add a new fwumdata tool to allows users to read, display, and modify FWU (Firmware Update) metadata from Linux userspace. It provides functionality similar to fw_printenv/fw_setenv but for FWU metadata. Users can view metadata, change active/previous bank indices, modify bank states, and set image acceptance flags. Configuration is done via fwumdata.config file.
Made a few change to mkfwumdata tool along the way.
