Fix cursor trail detaching from cursor when adjusting cursor scale

[Xiragi]

First PR.

Would fix #35734

I'm not sure if the tests are sufficient

[Xiragi]

These changes should fix the cursor trail disappearing on skin change

[Xiragi]

Implemented those change and it seems to be working as expected now. I've also simplified the test for it.

I've noticed another issue. The skin cursor trail still shows the old one during the pause menu.

1. Hit the first note and move the cursor around to generate a trail
2. Pause
3. Change Skin from Classic 2013 to Argon.
4. Unpause,
   5a. Current active cursor Skin trail, and playing normally correctly uses the new skin trail.
   5b. The trail for the play in the pause state still displays the old trail.

I'm not sure how to feel about forcing a texture update in the case that we switch between a legacy skin and a non-legacy skin. And at the same time, I feel like the PR is moving far from what it was intending to fix.

Out of scope, tracked separately at #7285.
