Restore log dumps for gradle OOM crashes, and set a value for MaxMetaspaceSize (#143085)
Re-sets two jvmargs that were getting cleared because we set a value for `-Xmx`. Could help with https://github.com/flutter/flutter/issues/142957. Copied from comment here https://github.com/flutter/flutter/issues/142957:
>Two random things I ran into while looking into this that might help:
>
>1. Gradle has defaults for a couple of the jvmargs, and setting any one of them clears those defaults for the others (bug here https://github.com/gradle/gradle/issues/19750). This can cause the "Gradle daemon to consume more and more native memory until it crashes", though the bug typically has a different associated error. It seems worth it to re-set those defaults.
>2. There is a property we can set that will give us a heap dump on OOM ([-XX:HeapDumpOnOutOfMemoryError](https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/clopts001.html))

Mostly just a find and replace from `find . -name gradle.properties -exec sed -i '' 's/\-Xmx4G/-Xmx4G\ \-XX:MaxMetaspaceSize=2G\ \-XX:+HeapDumpOnOutOfMemoryError/g' {} \;`, with the templates and the one test that writes from a string replaced by hand. I didn't set a value for `MaxMetaspaceSize` in the template files because I want to make sure this value doesn't cause problems in ci first (changes to the templates are essentially un-revertable for those who `flutter create` while the changes exist).

Example of calling platform services from Flutter

This project demonstrates how to connect a Flutter app to platform-specific services.

You can read more about accessing platform and third-party services in Flutter.

iOS

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or you can open ios/Runner.xcworkspace in Xcode and build/run the project as usual.

Android

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or to build with Android Studio, open the android folder in Android Studio and build the project as usual.

Windows

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or you can build once then open build\windows\platform_channel.sln in Visual Studio to build and run.
