[2D] SpriteResolver generates garbage every few frames when playing an animation

Package: 2D Animation

-

How to reproduce:
1. Open the attached project's Scene labeled "SampleScene"
2. Enter the Play Mode
3. Open the Profiler window (Window->Analysis->Profiler)
4. Input SpriteResolver.LateUpdate in the search field
5. Scrub through the Profiler graph
6. Inspect the GC Alloc value under the SpriteResolver.LateUpdate call

Expected result: Garbage is not generated every few frames
Actual result: Garbage is generated every few frames

Reproducible with: 3.2.6 (2019.4.27f1), 5.0.5 (2020.3.10f1), 6.0.3 (2021.1.8f1, 2021.2.0a17)
Couldn't test with: 2.0.0-preview.3 (Sprite Resolver is not available)

Notes:
- In Unity 2020.3.10f1, 64B of garbage is collected and it's more frequent
- In Unity 2021.1.8f1, 2021.2.0a17, either 272B or 236B of garbage is collected and it's less frequent

    Resolution Note (fix version 5.0.6):

    For Unity 2021.1 & Unity 2021.2 (2D Animation 6.x and 2D Animation 7.x)

    Sprite Resolver is only generating garbage if using an Animation Clip which animates Sprite Resolver and is created in Unity 2020.3 or earlier.
    A solution would be to upgrade your clips to animate SpriteResolver.SpriteKey instead of SpriteResolver.Category & SpriteResolver.Label. This will solve the garbage generation.
