Add word-at-a-time strlcpy using DETECTNULL for both the copy phase and the strlen tail when truncated. The copy loop aligns src and processes a register at a time, falling to bytewise for the last word containing the terminator. When truncated, the remaining src length is measured with a second word-at-a-time loop. strlcpy has 46 call sites in a typical kernel image (more than strcpy) and is not covered by newlib OPTSPEED, making it a high-value target.
