tools/nolibc/types: move the FD_* functions to macros in types.h

FD_SET, FD_CLR, FD_ISSET, FD_ZERO are often expected to be macros and
not functions. In addition we already have a file dedicated to such
macros and types used by syscalls, it's types.h, so let's move them
there and turn them to macros. FD_CLR() and FD_ISSET() were missing,
so they were added. FD_ZERO() now deals with its own loop so that it
doesn't rely on memset() that sets one byte at a time.
