 * Tokenized string entries are stored in this section. Each entry contains
 * the original string literal and the calculated token that represents it. In
 * the compiled code, the token and a compact argument list encoded in a
 * uint32_t are used in place of the format string. The compiled code
 * contains no references to the tokenized string entries in this section.
 *
 * The tokenized string entry format is specified by the
 * pw::tokenizer::internal::Entry class in
 * pw_tokenizer/public/pw_tokenizer/internal/tokenize_string.h.
 *
 * The section contents are declared with KEEP so that they are not removed
 * from the ELF. These are never emitted in the final binary or loaded into
 * memory.
