GameActivity PATCH: Don't read unicode via getUnicodeChar

The `unicodeChar` in `GameActivityKeyEvent` wasn't being exposed by
`android-activity` because we couldn't expose the unicode character in
the same way with the native-activity backend - due to how events are
received via an `InputQueue` that doesn't expose the underlying Java
references for the key events.

Now that we have a consistent way of supporting unicode character
mapping via `KeyCharacterMap` bindings it's redundant for the
`GameActivity` backend to call `getUnicodeChar` automatically for
each key press.
