Removed StringPiece::set and StringPiece::clear, as they have no absl::string_view equivalents.

This will allow for a more convenient transition to absl::string_view.

Calls to set StringPiece::set and StringPiece::clear were replaced with the StringPiece constructor as follows:

string_piece_foo.set(data, size) => string_piece_foo = StringPiece(data, size)
string_piece_foo.clear() => string_piece_foo = StringPiece()
