Reduce iterations and copies over inputs in ActionSpawn.

The current implementation copies all inputs into a list and then
iterates over them twice to remove filesets and manifests. We can
do the filtering in one pass instead and avoid the copying to a
list to save memory.

In addition, the Action.getInputs() method often returns inputs
stored in a NestedSet and we want to allow a caller to have
access to it, so that he isn't forced to flatten it. A call can
do that by checking if ActionSpawn.getInputFiles() is an instance
of NestedSetView.
