Update gradle memory properties in example and test projects (#163798)
Match the example and integration test apps to the the properties in the
`flutter create` template, updated in
https://github.com/flutter/flutter/pull/156201.

We discussed perhaps making this an auto-migration for existing Flutter
apps (if they've never edited the template from the old values), but it
probably makes sense for devs to manage this themselves depending on how
beefy the machine they are running on is.

Filed https://github.com/flutter/flutter/issues/163801 to show a nicer
message when the user hits this so they can manage
`java.lang.OutOfMemoryError: Java heap space` errors themselves.

Speculatively hoping this helps with the `Java heap space` build test
flakes

Integration tests

These tests are not hermetic, and use the actual Flutter SDK. While they don't require actual devices, they run flutter_tester to test Dart VM and Flutter integration.

Use this command to run (from the flutter_tools directory):

../../bin/cache/dart-sdk/bin/dart run test test/integration.shard

You need to have downloaded the Dart SDK in your Flutter clone for this to work. Running ../../bin/flutter will automatically download it.

Coverage exclusion

These tests are expensive to run and do not give meaningful coverage information for the flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.

Adding new test files

When adding a new test file make sure that it ends with _test.dart, or else it will not be run.
