Fix mania score conversion using score V1 accuracy
Partially addresses https://github.com/ppy/osu/discussions/26416

As pointed out in the discussion thread above, the total score
conversion process for mania was using accuracy directly from the
replay. In mania accuracy is calculated differently in score V1 than in
score V2, which meant that scores coming from stable were treated more
favourably (due to weighting GREAT and PERFECT equally).

To fix, recompute accuracy locally and use that for the accuracy
portion.

Note that this will still not be (and cannot be made) 100% accurate, as
in stable score V2, as well as in lazer, hold notes are *two*
judgements, not one as in stable score V1, meaning that full and correct
score statistics are not available without playing back the replay.

The effects of the change can be previewed on the following spreadsheet:
