Improve closest origin selection to include effects of rotation/flip

Browse Source 
Closes https://github.com/ppy/osu/issues/28237.

Solution as proposed here:
https://github.com/ppy/osu/pull/28089#issuecomment-2095372157

For flips and rotations by 90 degrees this does what you would expect it
to. For arbitrary rotations it *sort of kind of* attempts to do this but
the results are a bit wonky - probably still better than what was there
before, though?
