Kacie Bawiec da899c0cc4 Add support for Toggle Button accessibilityRole
Summary:
Changelog:
[General][Added] Add support for "togglebutton" accessibilityRole

# Context
The role for ToggleButton, which is needed on Android to implement toggle buttons correctly, is not currently supported.

# What does this diff do?
Adds support for accessibilityRole `"togglebutton"`.

On Android, this maps to class `"Android.widget.ToggleButton"`.

iOS does not have an equivalent trait for togglebutton, so I set it to be the same as setting `accessibilityRole="button"` for iOS.

# Caveats - checked vs selected
It seems to me like this role currently requires that you set `accessibilityState={{checked: true/false}}`. The behavior is strange when setting `selected` state, I think because on Android ToggleButtons are meant to use `checked` to indicate toggled on/off.

This is tricky because typically on iOS if you have a toggle button, you would use `selected` instead of `checked`, so RN users are likely to mess this up.

Possible solutions:
1. document that you should use `checked` state on Android for toggle buttons (and maybe throw a warning if someone passes in `selected`).
2. have RN ignore it if someone passes in accessibilityState `selected`, if this role is used.
3. Have RN convert passed in `selected` state to `checked` on the Android side.
