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).

Templates for Flutter Module

common

Written to root of Flutter application.

Adds Dart project files including pubspec.yaml.

android

library

Written to the .android/ hidden folder.

Contents wraps Flutter/Dart code as a Gradle project that defines an Android library.

Executing ./gradlew flutter:assembleDebug in that folder produces a .aar archive.

Android host apps can set up a dependency to this project to consume Flutter views.

gradle

Written to .android/ or android/.

Mixin for adding Gradle boilerplate to Android projects.

host_app_common

Written to either .android/ or android/.

Contents define a single-Activity, single-View Android host app with a dependency on the .android/Flutter library.

Executing ./gradlew app:assembleDebug in the target folder produces an .apk archive.

Used with either android_host_ephemeral or android_host_editable.

host_app_ephemeral

Written to .android/ on top of android_host_common.

Combined contents define an ephemeral (hidden, auto-generated, under Flutter tooling control) Android host app with a dependency on the .android/Flutter library.

host_app_editable

Written to android/ on top of android_host_common.

Combined contents define an editable (visible, one-time generated, under app author control) Android host app with a dependency on the .android/Flutter library.

ios

library

Written to the .ios/Flutter hidden folder.

Contents wraps Flutter/Dart code for consumption by an Xcode project.

iOS host apps can set up a dependency to this contents to consume Flutter views.

host_app_ephemeral

Written to .ios/ outside the Flutter/ sub-folder.

Combined contents define an ephemeral (hidden, auto-generated, under Flutter tooling control) iOS host app with a dependency on the .ios/Flutter folder contents.

The host app does not make use of CocoaPods, and is therefore suitable only when the Flutter part declares no plugin dependencies.

host_app_ephemeral_cocoapods

Written to .ios/ on top of host_app_ephemeral.

Adds CocoaPods support.

Combined contents define an ephemeral host app suitable for when the Flutter part declares plugin dependencies.
