KeyUp is raised after TextInput when the IME is enabled on macOS

[MrJul]

Describe the bug

On macOS, pressing a letter key when the IME is active raises the TextInput event, then the KeyUp event.
Since KeyDown is never raised (as expected in this case), ideally we shouldn't raise KeyUp either.

To Reproduce

Press any letter key inside a TextBox on macOS.

Expected behavior

Only TextInput is raised, not KeyUp.

We probably want to track _keyDownConsumedByInputContext or something _lastKeyDownEvent might also be useful. We might want to set _lastKeyDownEvent inside the keyUp handler.
