Add autofill service to save and retrieve password (#940)

Add autofill service to save and retrieve password

Fixes #831

Add support for Android autofill service and saving credit card information in KeyPass.

* **Autofill Service Implementation**
  - Add a new `<service>` element in `app/src/main/AndroidManifest.xml` for the autofill service.
  - Create a new file `KeyPassAutofillService.kt` to implement the `AutofillService` class.
  - Override necessary methods: `onFillRequest`, `onSaveRequest`, `onConnected`, and `onDisconnected`.
  - Fetch accounts and show as suggestions in `onFillRequest`.
  - Save account data in the database in `onSaveRequest`.

* **Utility Functions**
  - Update `GetAutoFillService.kt` to include functions to check if the autofill service is enabled and to enable the autofill service if it is not enabled.

* **Autofill Service Configuration**
  - Add a new XML file `autofill_service.xml` to configure the autofill service.
