Fix endianness of string literals (#4622)
* Fix endianness of string literals

To get correct and consistent encoding and decoding of string literals
on big-endian platforms, use spvtools::utils::MakeString and MakeVector
(or wrapper functions) consistently for handling string literals.

- add variant of MakeVector that encodes a string literal into an
  existing vector of words
- add variants of MakeString
- add a wrapper spvDecodeLiteralStringOperand in source/
- fix wrapper Operand::AsString to use MakeString (source/opt)
- remove Operand::AsCString as broken and unused
- add a variant of GetOperandAs for string literals (source/val)
... and apply those wrappers throughout the code.

Fixes  #149

* Extend round trip test for StringLiterals to flip word order

In the encoding/decoding roundtrip tests for string literals, include
a case that flips byte order in words after encoding and then checks for
successful decoding. That is, on a little-endian host flip to big-endian
byte order and then decode, and vice versa.

* BinaryParseTest.InstructionWithStringOperand: also flip byte order

Test binary parsing of string operands both with the host's and with the
reversed byte order.
