Why

To fix scrollview recent regression
Revert commits to fix ScrollView regression

Resolves #15171 and #15177

What

Revert 6bd0793 and 2cde3f1

Testing

Interestingly the bugs was not repro in playground then I found out a way to attach canary builds in gallery and tested there.

Below are the 4 commits made on scrollview:

2969c7b
2198313
2cde3f1
6bd0793

I tested in gallery from canary builds and found it's regressing after 2cde3f1

0.0.0-canary.969 -> OK -> 2969c7b

0.0.0-canary.970 -> OK -> 2198313

0.0.0-canary.974 -> BUG -> 2cde3f1

Most likely it's due to this line: https://github.com/microsoft/react-native-windows/blob/2cde3f11b7c67db52b6b56203cc3df560ac48ea7/vne…

To unblock release I will revert that commit.

But commit 6bd0793 is dependent on prev (2cde3f1) so will have to revert that too.

Hence reverting 2 commits and will pick up in future: snapToAlignment and snapToInterval
