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
