Allow ENCODE_FILE and DECODE_FILE to use no-copy conversion

They already did return their argument under some circumstances;
this change broadens it to further reduce allocation in common cases
(bug#40407).

* src/coding.c (convert_string_nocopy): New function.
(decode_file_name, encode_file_name): Use convert_string_nocopy.
* src/coding.h (ENCODE_FILE, DECODE_FILE): Note the nocopy semantics.
