Add scoring test scene for taiko

[bdach]

• Continuation of preparation for Classic scoring growth is too steep after scorev2 changes #23763
• Depends on Refactor scoring test scene for ruleset extensibility (and move existing instance to osu! ruleset project) #24821

Testing resources

taiko-scoring-resources.zip contains the following:

• TaikoTest.osu - a single taiko beatmap with 100 objects
• .osr files that correspond to replays set on the above beatmap
• .txt files containing extracts of stable total score after each judgement to cross-check.

Six different test cases are provided:

• perfect score:
  • ScoreV1Perfect
  • ScoreV2Perfect
• score with misses:
  • ScoreV1Misses
  • ScoreV2Misses
• score with misses and OKs:
  • ScoreV1MissesAndOks
  • ScoreV2MissesAndOks

which correspond to the test steps added to the scene. For cross-referencing, set ScoreMultiplier = 3 in the test.

Of note, in the above test cases, it seems that the final total for ScoreV2Misses is off by one (1) point at the final judgement, despite being fully correct up to then. I decided not to bother investigating this further.
