Do not use isFileEncryptedNativeOrEmulated() on Android 14 and later

[ebiggers]

Starting in Android 14 (U), the hidden static method StorageManager#isFileEncryptedNativeOrEmulated() is deprecated and has no callers other than robolectric. Therefore, stop depending on it. This unblocks the removal of this obsolete code.

@ebiggers Thanks for your contribution. LGTM. I only have some nits questions that we can discuss:

1. Can set maxSdk to SDK 34 as I found this API is still in AOSP main branch, and I think it was contained by Android 14. Is there any special reasons that you want to set maxSdk to SDK 33?
2. Could you add some necessary comments in this shadow method to describe the reason?

@hoisie Could you want to test it with internal code base?

It's as the commit message says: the Android framework stopped calling this method in Android 14 (API level 34). It was kept around only because of robolectric. If I understand correctly, that means that it was already unnecessary for robolectric to use it in API level 34. Hence, maxSdk = 33. Does that make sense, or do we need to wait another API level (which I'm worried would delay the removal of this obsolete code even further)?

@ebiggers I got it. sdk33 makes sense to me now. Sorry, I don't know the context of removing obsolete APIs, so I need @hoisie to approve this PR as I think he has more context of it.

Done now.

Sorry for the trouble, we will ensure this API does not get called
