Introduce WindowInfo::InputConfig flag to control input behavior

Instead of re-using layoutParams flags and layoutParam types and having
redundant information in WindowInfo, we add a new InputConfig flag that
the native input pipeline will use for all input window configurations.

This also reduces WindowInfo's size by converting booleans into flags.
