LinalgTilingPass: use PassRegistration with a pass constructor

Linalg tiling pass was introduced before PassRegistration with an optional pass
constructor.  It resorted to deriving a helper class from the origial pass
class in order to provide a default constructor with values obtained from
command line flags.  Use PassRegistration with the optional pass constructor
instead, which avoids declaring an additional class.
