[Android]Removed dependency with AppCompat. (#58527)
Summary:
I build using [Bazel](https://bazel.build/).
When I use `pytorch_android` in latest Android app, I get the following error due to dependencies:
```

This is due to conflict between `AndroidX` and `Support Library` on which `pytorch_android_torch` depends.
(In the case of `Gradle`, it is avoided by `android.useAndroidX`.)
I created [Android application](https://github.com/H1Gdev/android-bazel-app) for comparison.
At first, I updated `AppCompat` from `Support Library` to `AndroidX`, but `pytorch_android` and `pytorch_android_torchvision` didn't seem to need any dependencies, so I removed dependencies.
