This is a simple way of fixing the layout of scoring elements
overlapping due to different score display width requirements of
different scoring modes. It will only resolve the case where a user
hasn't customsied the layout of the default skins, but as this is a very
simple / low effort implementation for the most common scenario, I think
it makes sense.
Closes https://github.com/ppy/osu/issues/16067.
Came up when running the game after the recent breaking changes
(https://github.com/ppy/osu/pull/16722), where two template rulesets I
had loaded were erroring on startup but still being marked as available,
allowing them to crash the game on attempting to initiate relpay logic.
These cases are already handled for first-time ruleset loading via the
`GetTypes()` enumeration in `RulesetStore.addRuleset`, but when
consistency checking already present rulesets the only runtime
validation being done was `ruleset.CreateInstance()`, which does not
handle missing types or methods.
There are definitely going to be other actions used in the future, which
would immediately cause this mod to fail. Limiting handling to
left/right buttons only is the correct way forward.
