[Xamarin.Android.Build.Tasks] default to only 64-bit targets - #9179

We currently build for all 4 Android architectures by default. While
modern apps are more likely to run on `android-arm64` modern devices
or `android-x64` default emulator on x64 machines.
Let's drop 32-bit targets by default, and let customers opt into them.
This could significatly help `Release` build times, etc.
Customers could opt into all 4 by adding in their `.csproj`:
<RuntimeIdentifiers>android-arm;android-arm64;android-x86;android-x64</RuntimeIdentifiers>
Or in the case of a multi-targeted .NET MAUI project:
<RuntimeIdentifiers Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">android-arm;android-arm64;android-x86;android-x64</RuntimeIdentifiers>

There was a problem hiding this comment.
I think this is really old. It detected when we used to only build some of the ABIs on PRs. Think we can just remove this now.
