Provide backtrace for byte-ops car, cdr, setcar, setcdr, nth and elt

Include calls to these primitives from byte-compiled code in
backtraces.  For nth and elt, not all errors are covered.
(Bug#64613)

* src/bytecode.c (exec_byte_code): Add error backtrace records for
car, cdr, setcar, setcdr, nth and elt.
* src/data.c (syms_of_data): Add missing defsyms for car, setcar,
setcdr, nth and elt.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--error-frame, bytecomp-tests--byte-op-error-cases)
(bytecomp--byte-op-error-backtrace): New test.
