[Android] Flyoutmenu does not support tab navigation(accessibility/EAA)

### Description

We are in the process of finalizing our EAA implemention which requires certain functionality with regards to navigation in the app. However on Andoid it does not seem possible to navigate to the flyout open button or cycle through the flyout menu options with Tab. Anybody experienced this and implemented a workaround other then a custom flyout implementation?

### Steps to Reproduce

1. Create A new Maui Project
2. Add flyout items like:
`









`
3. Connect keyboard or emulate input to navigate through inputs on screen.
4. Cannot access or when opened cycle through the various input fields with TAB

Start with the MAUI Android flyout described in the reproduction steps and verify keyboard focus behavior using the listed Cats and Dogs flyout items. Investigate why Tab cannot reach the flyout button or cycle through its options; done means the button and menu items are reachable and traversable with Tab on Android.
