This is a rather barebones implementation, just to get this in place somehow at least. The logic is simple - 50% health or above shows pass layer, anything below shows fail layer.

This does not match stable logic all across the board because I have no idea how to package that. Stable defines "passing" in like fifty ways:

• in mania it's >80% HP (https://github.com/peppy/osu-stable-reference/blob/bb57924c1552adbed11ee3d96cdcde47cf96f2b6/osu!/GameModes/Play/Rulesets/Mania/RulesetMania.cs#L333-L336)
• in taiko it's >80% accuracy (https://github.com/peppy/osu-stable-reference/blob/bb57924c1552adbed11ee3d96cdcde47cf96f2b6/osu!/GameModes/Play/Rulesets/Taiko/RulesetTaiko.cs#L486-L492)
• there's also the part where "geki additions" will unconditionally set passing state (https://github.com/peppy/osu-stable-reference/blob/bb57924c1552adbed11ee3d96cdcde47cf96f2b6/osu!/GameModes/Play/Player.cs#L3561-L3564)
• and also the part where at the end of the map, the final passing state is determined by checking whether the user passed more sections than failed (https://github.com/peppy/osu-stable-reference/blob/bb57924c1552adbed11ee3d96cdcde47cf96f2b6/osu!/GameModes/Play/Player.cs#L3320)

The biggest issues of these are probably the first two, and they can probably be fixed, but would require a new member on Ruleset and I'm not sure how to make one look, so I'm not doing that at this time pending collection of ideas on how to do that.
