I2_Spacing - Changing the spacing value to a higher number causes the scrolling performance to be slower.

### Description

If you change the spacing value to a higher number, the scrolling performance of the list would be slower.

Affected case:
I2 - Vertical list (Item Spacing)
I2 - Horizontal list (Item Spacing)
I2 - Vertical grid (Horizontal Item Spacing and Vertical Item Spacing)
I2 - Horizontal grid (Horizontal Item Spacing and Vertical Item Spacing)

### Steps to Reproduce

1. Deploy https://devdiv.visualstudio.com/Pkgs/_git/VS.TestAssets.Xaml?path=/Assets/Projects/ManualMauiTests on Android platform (debug or release mode).
2. Click I2 -> Vertical list (Spacing) or any page where you can change the spacing value.
3. Change the spacing value to a higher number (ex. 100), observe that the scrolling performance is slower than when you set it to 0 or a lower number.

Actual Behavior:
Change in the spacing value causes slower scrolling performance.


Expected Behavior:
Change in the spacing value would not cause any changes in the scrolling performance.

### Version with bug

9.0.60-ci.main.25165.2

### Is this a regression from previous behavior?

Not a regression, the issue also reproduces on 9.0.50 & 9.0.40 & 9.0.0 & 8.0.100.

### Affected platforms

Android

Start by deploying the linked VS.TestAssets.Xaml ManualMauiTests project on Android and reproduce the I2 vertical and horizontal list/grid cases with spacing 0 and 100. Compare scrolling performance across the affected cases; done means changing spacing no longer causes slower scrolling, with the relevant behavior covered by a regression check.
