cbfs: Add "struct" file type and associated helpers

This patch adds functionality to compile a C data structure into a raw
    binary file, add it to CBFS and allow coreboot to load it at runtime.
    This is useful in all cases where we need to be able to have several
    larger data sets available in an image, but will only require a small
    subset of them at boot (a classic example would be DRAM parameters) or
    only require it in certain boot modes. This allows us to load less data
    from flash and increase boot speed compared to solutions that compile
    all data sets into a stage.

Each structure has to be defined in a separate .c file which contains no
    functions and only a single global variable. The data type must be
    serialization safe (composed of only fixed-width types, paying attention
    to padding). It must be added to CBFS in a Makefile with the 'struct'
    file processor.
