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.

spirv-opt: Switch from Vulkan.DebugInfo to Shader.DebugInfo (#4493)
Includes:
- Shift to use of spirv-header extinst.nonsemantic.shader grammar.json
- Remove extinst.nonsemantic.vulkan.debuginfo.100.grammar.json
- Enable all optimizations for Shader.DebugInfo

Also fixes scalar replacement to only insert DebugValue after all
OpVariables. This is not necessary for OpenCL.DebugInfo, but it is
for Shader.DebugInfo.

Likewise, fixes Private-to-Local to insert DebugDeclare after all
OpVariables.

Also fixes inlining to handle FunctionDefinition which can show up
after first block if early return processing happens.

Add interpolate legalization pass (#4220)
This pass converts an internal form of GLSLstd450 Interpolate ops
to the externally valid form. The external form takes the lvalue
of the interpolant. The internal form can do a load of the interpolant.
The pass replaces the load with its pointer. The internal form is
generated by glslang and possibly other frontends for HLSL shaders.
The new pass is called as part of HLSL legalization after all
propagation is complete.

Also adds internal interpolate form to pre-legalization validation

Validate SPV_KHR_workgroup_memory_explicit_layout (#4128)
* Validate SPV_KHR_workgroup_memory_explicit_layout

* Check if SPIR-V is at least 1.4 to use the extension.

* Check if either only Workgroup Blocks or only Workgroup non-Blocks
  are used.

* Check that if more than one Workgroup Block is used, variables are
  decorated with Aliased.

* Check layout decorations for Workgroup Blocks.

* Implicitly use main capability if the ...8BitAccess or
  ...16BitAccess are used.

* Allow 8-bit and 16-bit types when ...8BitAccess and ...16BitAccess
  are used respectively.

* Update SPIRV-Headers dependency

Bump it to include SPV_KHR_workgroup_memory_explicit_layout.

* Add option to validate Workgroup blocks with scalar layout

Validate the equivalent of scalarBlockLayout for Workgroup storage
class Block variables from SPV_KHR_workgroup_memory_explicit_layout.
Add option to the API and command line tool.

Remove WebGPU support (#4108)

Allow DebugTypeTemplate for Type operand (#3702)
Some OpenCL.DebugInfo.100 instructions such as DebugGlobalVariable
and DebugLocalVariable have the Type operand. This commit allows them to
use DebugTypeTemplate for the Type operand.

OpenCL.DebugInfo.100 DebugTypeArray with variable size (#3549)
The updated OpenCL.DebugInfo.100 spec says that we can use
variable for "Component Count" operand of DebugTypeArray i.e.,
DebugLocalVariable or DebugGlobalVariable. This commit updates spirv-val
based on the spec update.

Add support for SPV_KHR_non_semantic_info (#3110)
Add support for SPV_KHR_non_semantic_info

This entails a couple of changes:

- Allowing unknown OpExtInstImport that begin with the prefix `NonSemantic.`
- Allowing OpExtInst that reference any of those sets to contain unknown
  ext inst instruction numbers, and assume the format is always a series of IDs
  as guaranteed by the extension.
- Allowing those OpExtInst to appear in the types/variables/constants section.
- Not stripping OpString in the --strip-debug pass, since it may be referenced
  by these non-semantic OpExtInsts.
- Stripping them instead in the --strip-reflect pass.

* Add adjacency validation of non-semantic OpExtInst

- We validate and test that OpExtInst cannot appear before or between
  OpPhi instructions, or before/between OpFunctionParameter
  instructions.

* Change non-semantic extinst type to single value

* Add helper function spvExtInstIsNonSemantic() which will check if the extinst
  set is non-semantic or not, either the unknown generic value or any future
  recognised non-semantic set.

* Add test of a complex non-semantic extinst

* Use DefUseManager in StripDebugInfoPass to strip some OpStrings

* Any OpString used by a non-semantic instruction cannot be stripped, all others
  can so we search for uses to see if each string can be removed.
* We only do this if the non-semantic debug info extension is enabled, otherwise
  all strings can be trivially removed.

* Silence -Winconsistent-missing-override in protobufs
