[android] bring back $(AndroidLinkResources) by default (dotnet#10153)

This reverts commit af8e7ce.

Thanks to:

`int[]` fields now work in .NET 7, when you enable
`$(AndroidLinkResources)`. Our thought is to try this by default in
.NET 7 RC 2.

Different in app size:

    > apkdiff -f .\before.apk .\after.apk
