Move LaunchContainer enum to extension_constants.h.

Move the Chrome-specific LaunchContainer enum out of
extensions/common/constants.h and into
chrome/common/extensions/extension_constants.h (it can't
live under chrome/browser/extensions since it's used by
AppLaunchInfo). For consistency, also move the LaunchType
enum to extension_constants.h.

Rename LaunchContainer's values from LAUNCH_* to
LAUNCH_CONTAINER_*, and also rename the LAUNCH_TYPE_* values
in AppContextMenu to USE_LAUNCH_TYPE_* to avoid confusion
with the LaunchType enum.
