Subject: ArmPlatformPkg/BootMonFs: Provide mechanism to get BootMonFS file
 information

Add additional structure to get file meta-data information from BootMonFS
based files. AXF files are processed by the Flash loader and the ELF header
stripped. The relevant information is stored in the file-system.
