[UGUI] Image with crunch compression can still have a modified alphaHitTestMinimumThreshold

The alphaHitTestMinimumThreshold can be modified from script even if the image is using crunch compression. This make the ReadPixels invalid.

Steps to reproduce:
1. Import the package.
2. Press Play.
- Image on the left (green) is compressed and will change its alphaHit, which should be invalid
- Image on the right (red) will chaneg its alphaHit (valid), then change its sprite to the green one, which is compressed (invalid)
3. Hover both images
4. Notice the weird behavior of the hovering, but no errors are displayed
