cbfs: Add unverified_area APIs

This patch adds a new ..._unverified_area_... group of functions to the
cbfs_map/_load/_alloc() APIs. These functions can be used to access
custom FMAP sections and are meant to replace the existing
cbfs_locate_file_in_region(). The name is intended to highlight that
accesses through this API will not be verified when CBFS_VERIFICATION is
enabled and should always be treated as if they may return malicious
data. (Due to laziness I'm not adding the combination of this API with
the ..._type_... variant at this point, since it seems very unlikely
that we'll ever have a use case for that. If we ever do, it should be
easy to add later.)

(Also remove the 'inline' from cbfs_file_hash_mismatch(). I'm not sure
why I put it there in the first place, probably a bad copy&paste.)
