refactor: add xmemcpyz() and use it in place of some xstrlcpy() (#28422)

Browse Source 
Problem:  Using xstrlcpy() when the exact length of the string to be
          copied is known is not ideal because it requires adding 1 to
          the length and an unnecessary strlen().
Solution: Add xmemcpyz() and use it in place of such xstrlcpy() calls.
