Pattern bouncer refactor: motion layout - change constraints on rotate

- refactored Pattern bouncer into a single motion layout
- transition between landscape or portrait constrains on rotate

why are we doing this?
- to add support for landscape bouncers on small screens

"Split" bouncer constraints (https://hsv.googleplex.com/5351602346000384) will be used on small landscape screens only

"Single" bouncer constraints (https://hsv.googleplex.com/6007067992129536) are used otherwise, such as for large screen port/land and small screens port - this is the same as the previous behaviour.

Use of "split or single" bouncer constraints is not strictly related to device orientation.

Flag:
WHEN FLAG OFF - old portrait layout always used
WHEN FLAG ON - new layout uses, constraints updated to match current orientation (once per rotate, once on device posture change, and once after inflate)
