FileAction was previously a nested class in ProcessLaunchInfo. This led to some unfortunate style consequences, such as requiring the AddPosixSpawnFileAction() funciton to be defined in the Target layer, instead of the more appropriate Host layer. This patch makes FileAction its own independent class in the Target layer, and then moves AddPosixSpawnFileAction() into Host as a result.
