Uno: Binding TestBox.Text property using `OneWay` mode is ignored by binding engine

[MelbourneDeveloper]

Current behavior

Binding mode is defaulting to TwoWay on WASM while UWP is OneWay

Expected behavior

Binding mode defaults to OneWay - and should honor it.

How to reproduce it (as minimally and precisely as possible)

Run sample. UWP is one way, but WASM is TwoWay

Just reproduced easily on the Playground on this address:

I also confirm the problem is present on both iOS and Wasm. Can't reproduce on Android.
