feat: Add a button to delete vanilla app after patching apk

Type

Functionality

Issue

When you try to install the patched apk you get a warning because the vanilla app and the patched apk signature are different.

Feature

There's two ways to solve it.

1. Show a button to delete the vanilla app if the vanilla app signature and patched apk signature conflicts.
   OR
2. Add a delete vanilla app button in the 3 dots menu on the top right. (If the signature comparing process won't be added.)

Motivation

To improve users UX.

Currently users have to patch app -> go to home screen -> delete vanilla app -> come back to ReVanced Manager and press 'install'.
