switch to android-game-sdk-rs grafted repo at v2.0.2

Also includes our patches on top (branch android-activity-2.0.2). This
is mainly to test to make sure everything is still working. We will
switch to the android-activity-4.0.0 branch when we're done

+# android-games-sdk-rs
+
+This is a grafted version of [android-games-sdk-rs][agdk].
+
+The purpose of android-games-sdk-rs is to track our patches on top of the Android Game Development Kit (AGDK) so that it is easier to update to new upstream versions.
+
+## Updating to new agdk version checklist
+
+This is a basic checklist for things that need to be done before updating to a new agdk version:
+
+- [ ] Ensure all patches applied to the local repo have been backported (see section below on backporting patches)
+- [ ] Rebase patches on top of a new *release* version of agdk. If you're not sure which version you should be rebasing on, open an issue.
+- [ ] Copy any new files over from the new version using the [copy_files](./copy_files) script (see section below on copying files)
+- [ ] Update [build.rs](../build.rs) with any new includes and src files
+- [ ] Regenerate ffi bindings using [generate_bindings.sh](./generate_bindings.sh)
+
+## Backporting patches
+
+Changes made to these files must be backported to [android-games-sdk-rs][agdk], otherwise they will be lost when updating to newer upstream versions. This can be done like so (running from the project root):
+
+```bash
+git format-patch -o ~/agdk-patches last-import.. -- android-activity/android-games-sdk
+```
+
+When applying on the [android-games-sdk-rs][agdk] side:
+
+```bash
+git checkout android-activity-4.0.0
+git am -p3 ~/agdk-patches/*.patch
+```
+
+Once these are applied on top of the current imported agdk version (in this example 4.0.0). Then they can be rebased onto future agdk versions easily.
+
+## Copying files from agdk
+
+When updating to a new version of upstream agdk properly, you can use the [copy_files](./copy_files) script.
+
+This script takes in a list of files from [file_list.txt](./file_list.txt), and grafts those files into the local directory. This ensures that pathes are aligned so that patching is easier.
