Add rotation support to launch animations
This only adds support for launch animations. Recents
requires some auxiliar work.
Adds a rotation parameter to the animation targets that
only gets used by shell transitions. If this is non-zero,
launcher will transform it's coordinates relative to that
provide rotation.
Bug: 179308296
Test: Launch and exit apps with different orientation from
default (portrait).
