lib.strings.normalizePath: Deprecate for path values

Browse Source 
There's no need to call this function on path data types, and it's
confusing with the new lib.path library functions

lib.strings.normalizePath: The argument (${toString s}) is a path value, but only strings are supported.
Path values are always normalised in Nix, so there's no need to call this function on them.
This function also copies the path to the Nix store and returns the store path, the same as "''${path}" will, which may not be what you want.
This behavior is deprecated and will throw an error in the future.''
