Lioncash 28bef31ea8 vfs_concat/vfs_layered: Remove friend declarations from ConcatenatedVfsFile
Given these are only added to the class to allow those functions to
access the private constructor, it's a better approach to just make them
static functions in the interface, to make the dependency explicit.
