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.

Cleanup includes. (#1795)
This Cl cleans up the include paths to be relative to the top level
directory. Various include-what-you-use fixes have been added.

Simplify validation ProcessInstruction (#1786)
This CL moves most of the logic out of validation ProcessInstruction and
groups it into validate. This places all of the validation logic in the
same place making it clearer what is running.

The Instruction class is changed to allow setting the function and block
after creation.

Remove instruction_counter from ValidationState. (#1781)
The instruction counter is the same as the size of the
ordered_instruction list when we insert a new instruction. This Cl
removes instruction_counter_ and uses that instead.

Remove using std::<foo> statements. (#1756)
Many of the files have using std::<foo> statements in them, but then the
use of <foo> will be inconsistently std::<foo> or <foo> scattered
through the file. This CL removes all of the using statements and
updates the code to have the required std:: prefix.

Move the validation code into the val:: namespace (#1682)
This CL moves the validation code to the val:: namespace. This makes it
clearer which instance of the Instruction and other classes are being
referred too.

Change libspirv to spvtools namespace (#1678)
This CL changes all of the libspirv namespace code to spvtools to match
the rest of the code base.

[val] Add extra context to error messages. (#1600)
[val] Add extra context to error messages.

This CL extends the error messages produced by the validator to output the
disassembly of the errored line.

The validation_id messages have also been updated to print the line number of
the error instead of the word number. Note, the error number is from the start
of the SPIR-V, it does not include any headers printed in the disassembled code.

Fixes #670, #1581
