vim-patch:partial:9.2.0193: using copy_option_part() can be improved (#38369)

Problem:  using copy_option_part() can be improved
Solution: Refactor and use the return value of copy_option_part() to
          avoid strlen() calls (John Marriott).

In addition, this commit includes the following changes:

memline.c:
- In recover_names():
  - Replace calls to vim_strsave() with vim_strnsave() for the literal
    strings
  - Use a string_T to store local variable dir_name.

bufwrite.c:
- In buf_write()
  - move variable wp to where it is used.

help.c:
- In fix_help_buffer():
  - replace call to add_pathsep() with after_pathsep()

optionstr.c:
- In export_myvimdir():
  - use a string_T to store local variable buf
  - replace call to add_pathsep() with after_pathsep()

scriptfile.c:
- In do_in_path():
  - use a string_T to store local variable buf
  - measure the lengths of prefix and name once before the while loop
  - replace call to add_pathsep() with after_pathsep()
  - move some variables closer to where they are used

spellfile.c:
- In init_spellfile():
  - use a string_T to store local variable buf
