Add AGP8 support by adding buildConfig = true to buildFeatures

[pvegh]

Description

Upgrading to Android Gradle Plugin 8.1 and trying not to use the global flag
android.defaults.buildfeatures.buildconfig=true
which leads to slower builds than defining this only in needed modules
I'm getting the error:

* What went wrong:
A problem occurred configuring project ':react-native-gesture-handler'.
> defaultConfig contains custom BuildConfig fields, but the feature is disabled.
  To enable the feature, add the following to your module-level build.gradle:
  `android.buildFeatures.buildConfig true`

Fix: please add the flag

buildFeatures {
        buildConfig = true
    }

Other projects do something like this:

def agpVersion = com.android.Version.ANDROID_GRADLE_PLUGIN_VERSION
    if (agpVersion.tokenize('.')[0].toInteger() >= 7) {
        namespace "com.horcrux.svg"
    }

to build.gradle for AGP >= 8.1

Steps to reproduce

1. Upgrade to AGP 8.1
2. add android.defaults.buildfeatures.buildconfig=true to gradle.properties (done by AGP upgrade wizard in AS)
3. ./gradlew assDebug

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

Can't do a repro sorry, I'm not into the RN game that much. Just reporting a problem here as well as I can with a possible fix

[pvegh]

Can you please take a look at this? I know there's no repro here but it should be straightforward anyway

[pvegh]

RN Thread about this: react-native-community/discussions-and-proposals#671

[pvegh]

In my opinion it doesn't need a repro, it's a build simple feature with full description what is missing.
Also I'm not an RN person, I just need the android part to behave well.

Created a PR, probably need some help since I don't usually do this. #2599

[pvegh]

Would a patch version with this be possible?
