Implement StringPieceHasSubstrMatcher.

Implement StringPieceHasSubstrMatcher.

This makes it possible to define a HasSubstr() that is compatible with
base::StringPiece arguments, thus reducing divergence between upstream and
Chromium code.  (In the upstream codebase, base::StringPiece can be implicitly
converted into std::string, so there is no need for this workaround.)
