bisect--helper: remove unused options

Browse Source 
'git-bisect.sh' used to have a 'bisect_next_check' to check if we have
both good/bad, old/new terms set or not.  In commit 129a6cf344
(bisect--helper: `bisect_next_check` shell function in C, 2019-01-02),
a subcommand for bisect--helper was introduced to port the check to C.
Since d1bbbe45df (bisect--helper: reimplement `bisect_run` shell
function in C, 2021-09-13), all users of 'bisect_next_check' was
re-implemented in C, this subcommand was no longer used but we forgot
to remove '--bisect-next-check'.

'git-bisect.sh' also used to have a 'bisect_write' function, whose
third positional parameter was a "nolog" flag.  This flag was only used
when 'bisect_start' invoked 'bisect_write' to write the starting good
and bad revisions.  Then 0f30233a11 (bisect--helper: `bisect_write`
shell function in C, 2019-01-02) ported it to C as a command mode of
'bisect--helper', which (incorrectly) added the '--no-log' option,
and convert the only place ('bisect_start') that call 'bisect_write'
with 'nolog' to 'git bisect--helper --bisect-write' with 'nolog'
instead of '--no-log', since 'bisect--helper' has command modes not
subcommands, all other command modes see and handle that option as well.
This bogus state didn't last long, however, because in the same patch
series 06f5608c14 (bisect--helper: `bisect_start` shell function
partially in C, 2019-01-02) the C reimplementation of bisect_start()
started calling the bisect_write() C function, this time with the
right 'nolog' function parameter. From then on there was no need for
the '--no-log' option in 'bisect--helper'. Eventually all bisect
subcommands were ported to C as 'bisect--helper' command modes, each
calling the bisect_write() C function instead, but when the
'--bisect-write' command mode was removed in 68efed8c8a
(bisect--helper: retire `--bisect-write` subcommand, 2021-02-03) it
forgot to remove that '--no-log' option.
'--no-log' option had never been used and it's unused now.

Let's remove --bisect-next-check and --no-log from option parsing.
