Implement a feature that installs a cc_test's dependencies into a standalone folder.

This is the implementation of go/standalone-native-device-tests

This feature is disabled by default. To enable it, the `standalone_test` option needs to be added in the Android.bp file.

Example:

```
cc_test {
  ...
  standalone_test: true,
  ...
}
```
