Respect narrowed buffers when parsing JSON (bug#77325)

* src/json.c (Fjson_insert): Simplify 'memcpy' argument.
(Fjson_parse_buffer): Only read to ZV, not all the way to Z.
* test/src/json-tests.el (with-all-gap-positions-in-temp-buffer):
New macro.
(json-parse-buffer/restricted): New test.

(cherry picked from commit 67e34f0ed8f6d3bbc78187a18f71010c70e10426)
