Added StrContains, StartsWith, and EndsWith functions to str_util.h.

Marked contains, starts_with, ends_with, and consume StringPiece methods as deprecated.

This will allow tensorflow::StringPiece to be more easily replaced with absl::string_view (once the deprecated methods are removed) as absl::string_view does not contain those methods.
