Fix collectExtraIntentKeys for nested LazyValue who is of custom class

collectExtraIntentKeys calls BaseBundle.get(key) method to try to
find out if the intent contains extra intent. But if the Bundle
contains a LazyValue of custom class, and the bundle's classLoader
is not PathClassLoader (points to the custom class's path), then
it would fail - a BadParcelableException would throw.

ActivityThread only sets the intent's mExtra's classLoader
correctly. This leaves nested intents (1+ levels deep) with default
bootClassLoader. This could also happen if the bundle comes from
other IPC methods (not as a starting intent's extra bundle).

This CL fixed this issue by handling The BadParcelableException. This skips collectExtraIntentKeys method for custom and nested class objects. See go/prevent-intent-redirect-customclass for details.
