Fix inverted NOCOPY encode/decode parameter (bug#40407)
In {encode,decode}-coding-string, the NOCOPY parameter had the
opposite effect to what was intended and documented. This 18 year old
bug (introduced in 4031e2bf0a) only affected calls with CODING-SYSTEM
being nil.
* src/coding.c (code_convert_string): Correct use of NOCOPY.
* test/src/coding-tests.el (coding-nocopy-trivial): New test.
