This patch contains several minor cleanups related to compiler.h: - Replace __always_unused() (which is a Linux-specific concept that doesn't make sense without also having __maybe_unused(), and had zero uses in the codebase) with __unused() which moves here from helpers.h - Add __underscores__ to the names of all attributes in the compiler attribute shorthand macros. This is necessary to make them work in files where the same name was already used for an identifier (e.g. cbfstool/cbfs.h's `unused` array of file types). - Remove libpayload's own copy of compiler.h and make it directly pull in the commonlib/bsd copy.
