LayoutManager controls child bounds. Added SetChildBounds and several listener methods to LayoutManager class. They will be used to implement more sophisticated behavior.

Implemented DefaultContainerLayoutManager.

Added test_support_aura component so that it can be shared
between aura and aura_shell.

Fixed component build for aura_shell_unittests

BUG=none
TEST=default_container_layout_manager_unittests.
