layers: Change pNext validation error to warning

Change the severity level of the parameter_validation layer's pNext
parameter validation messages from error to warning.  Also add an
explanation that the warning is derived from the Valid Usage
language from version X of the Vulkan spec/header, which may be out
of date:

This warning is based on the Valid Usage documentation for version %d
of the Vulkan header.  It is possible that you are using a struct
from a private extension or an extension that was added to a later
version of the Vulkan header, in which case your use of pNext is
perfectly valid but is not guaranteed to work correctly with
validation enabled
