cbfstool: Make add-stage support multiple loadable segments
For x86 eXecute-In-Place (XIP) pre-memory `.data` section support, we have to use an extra segment as the VMA/LMA of the data is different than the VMA/LMA of the code. To support this requirement, this patch makes cbfstool: 1. Allow the load of an ELF with an extra segment 2. Makes add-stage for XIP (cf. parse_elf_to_xip_stage()) write its content to the output binary. To prevent the creation of unsuitable binaries, cbfstool verifies that the LMA addresses of the segments are consecutives. TEST=XIP pre-memory stages with a `.data` section have the `.data` section covered by a second segment properly included right after the code.
