Make ADT use the new layoutlib API.

ADT now exclusively use the new API.
The older platforms that still use the old API are
accessed through a compatibility layer provided by the class
LayoutBridgeWrapper that converts the old to the new API (both
input and output).

The wrapper and the loading code for the bridge have moved
to layoutlib_utils, but into the ide.common package.
Layoutlib_utils is to be renamed ide-common later.

.sdk.LoadStatus has moved into .ide.common too since
it's used by the bridge loading code. As we'll move
more code into ide-common it's ok to have it there anyway.

Also did some minor fix to the API:
- missing implementation of ViewInfo
- Made a singleton for SUCCESS state of SceneResult.
