[Debloater] Initial UI

The list is taken from https://github.com/0x192/universal-android-debloater


and kept intact for now.

Debloater can be accessed from the three-dots menu in the Main page.

Colour codes for the list:
- Dark cyan: The app is safe to remove. It does not necessarily mean that the
  app should be removed as it is always up to the preferences of the user.
- Sand colour: The app is safe to remove, but removing it might break one or
  more features.
- Orange colour: The app may or may not be safe to remove.
- Red colour: The app is not safe to remove. It is not clear as to why these
  apps are listed in the UAD list.

Batch operations:
- Uninstallation
- Enable/disable
- Save APK
- Create new profile
- Add to profile

In addition to the typical search option, there are several filtering options
available in this page:
1. Categories: AOSP, OEM, Carrier/ISP, Google, Miscellany and Pending
2. Types: Safe (i.e. safe to remove), Replace (i.e. should be replaced with alternatives), Caution (i.e. generally safe to remove but no guarantees), Unsafe (may cause bootloop)
3. Other: User apps, System apps (mutually exclusive), Installed apps and Uninstalled apps (mutually exclusive).
