feat(libc): add support for fallthrough statement
Modern C compilers warn about unannotated switch/case fallthrough code,
and require either a comment with some magic words, or an explicit
compiler attribute.
Since some TF-A static analysis CI check suggests having a "fallthrough;"
statement instead of a comment, introduce a macro that implements that
statement, and emits the proper compiler attribute.
