tools: Add support for fwumdata tool
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.
