Issue: Flutter needs to declare `abiFilters` for only supported architectures by default
Labels: platform-android,tool,c: proposal,P2,team-android,triaged-android

### Steps to reproduce

Flutter does not set `abiFilters` in its default `flutter create` template, which means that without intervention, apps published to the Play Store all declare that they will run on x86 (x86_32), which is not (and never will be) supported by Flutter.

Users with x86 devices who install the app from Google Play will be met with a crash, which is logged in Crashlytics as `java.lang.UnsatisfiedLinkError: dlopen failed: library "libflutter.so" not found`.

This issue is forked from #151638 at the request of @danagbemava-nc, who said:

> It appears there was an attempt to add this in https://github.com/flutter/flutter/pull/135529 but it was later reverted in https://github.com/flutter/flutter/pull/142089 and it must have dropped off everyone's radar. Can you file a new proposal for adding it?

### Expected results

Flutter should opt-in to all of its supported architectures by default using `ndk.abiFilters`.

### Actual results

Failing to set `abiFilters` means that the app can run on all architectures supported on Google Play, which simply does not reflect reality.

### Code sample

`android/app/build.gradle` should include something like this when `flutter create` is called:

```dart
android {
    defaultConfig {
        ndk.abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86_64'
    }
}
```
