The "xopts" variable uses a custom array with ALLOC_GROW(). Using a
strvec simplifies things a bit. We need fewer variables, and we can also
ditch our custom parseopt callback in favor of OPT_STRVEC().
As a bonus, this means that "--no-strategy-option", which was previously
a silent noop, now does something useful: like other list-like options,
it will clear the list of -X options seen so far. This matches the
behavior of revert/cherry-pick, which made the same change in fb60b9f37f
(sequencer: use struct strvec to store merge strategy options,
2023-04-10).
