[PM-6552] Fix for Android Window issues when opening Autofill/Accessibility

[dinisvieira]

Type of change

• Bug fix
• New feature development
• Tech debt (refactoring, code cleanup, dependency upgrades, etc)
• Build/deploy pipeline (DevOps)
• Other

Objective

There are still several edge cases in which the app should try to execute the navigation after showing the HomePage and doesn't.
As an alternative we are trying to always try to Navigate when CreateWindow is launched on Android.

Code changes

Removed several of the Window Workarounds for Android. Now always relying on the AndroidNavigationRedirectPage
AndroidNavigationRedirectPage now more resilient to failure and navigates to HomePage as fallback.

• App.xaml.cs: Removed a lot of the previous workarounds which should now be replaced with just using always AndroidNavigationRedirectPage
• AndroidNavigationRedirectPage.xaml.cs: Made redirection a bit more resilient and with fallback to just Navigate to HomePage
• AutofillSettingsPageViewModel.android.cs: Removed previous workaround for Accessibility Settings as it's no longer need
• ResumeWindow.cs: AutofillWindow and MainWindow is no longer needed as we don't reuse or differentiate anymore
