[TF:XLA] Split literal_util into {literal, literal_util}.

Currently Literal classes sits in literal_util.{h,cc} instead of literal.{h,cc}.
It also contains helper functions that are better fit to be their own separate
class/namespace. This change starts this process by moving most static factory
methods to LiteralUtil namespace.
