- Add initialization check for secondary animator provider in MaterialVisibility so subclasses no longer need to explicitly call MaterialVisibility#initialize.

(cherry picked from commit e63cae59fb71b580399ab7479697b5493f7a9dd1)
This updaes the remaining transitions to compose themselves of two animators instead of two visibility transitions. This also removes the context parameter from MaterialFadeThrough, MaterialFade and MaterialSharedAxis' constructors.
