commonlib: cbfs: Add CBFS attribute support

This patch adds support for the CBFS attributes that were already
    introduced in cbfstool and libpayload. I'm only copy&pasting the header
    definitions needed for this once more. Really, we should be unifying the
    definitions (and possibly part of the code) from cbfstool with
    commonlib, but apparently that hadn't been done when this feature was
    introduced and I don't really have time to do it cleanly now.

Also add a function to extract info from the compression attribute,
    which can then be used to run cbfs_load_and_decompress() on the file.
