Support for float atomics on RWByteAddressBuffer (#1502)

* Fix premake5.lua so it uses the new path needed for OpenCLDebugInfo100.h

* Keep including the includes directory.

* Added the spirv-tools-generated files.

* We don't need to include the spirv/unified1 path because the files needed are actually in the spirv-tools-generated folder.

* Put the build_info.h glslang generated files in external/glslang-generated. Alter premake5.lua to pick up that header.

* First pass at documenting how to build glslang and spirv-tools.

* Improved glsl/spir-v tools README.md

* Added revision.h

* Change how gResources is calculated.
Update about revision.h

* Update docs a little.

* Split out spirv-tools into a separate project for building glslang. This was not necessary on linux, but *is* necessary on windows, because there is a file disassemble.cpp in spirv-tools and in glslang, and this leads to VS choosing only one. With the separate library, the problem is resolved.

* Fix direct-spirv-emit output.

* Update to latest version of spirv headers and spirv-tools.

* Upgrade submodule version of glslang in external.

* Add fPIC to build options of slang-spirv-tools

* WIP adding support for InterlockedAddFp32

* Upgrade slang-binaries to have new glslang.

* Fix issues with Windows slang-glslang binaries, via update of slang-binaries used.

* WIP - atomicAdd. This solution can't work as we can't do (float*) in glsl.

* WIP on atomic float ops.

* Added checking for multiple decls that takes into account __target_intrinsic and __specialized_for_target.
First pass impl of atomic add on float for glsl.

* Split __atomicAdd so extensions are applied appropriately.

* Made Dxc/Fxc support includes.
Use HLSL prelude to pass the path to nvapi
Added -nv-api-path

* Refactor around IncludeHandler and impl of IncludeSystem

* slang-include-handler -> slang-include-system
Have IncludeHandler/Impl defined in slang-preprocessor

* Small comment improvements.

* Document atomic float add addition in target-compatibility.md.

* CUDA float atomic support on RWByteAddressBuffer.

* Add atomic-float-byte-address-buffer-cross.slang

* Removed inappropriate-once.slang - the test is no longer valid when a file is loaded and has a unique identity by default. A test could be made, but would require an API call to create the file (so no unique id).
Improved handling of loadFile - uses uniqueId if has one.

* Work around for testing target overlaps - to avoid exceptions on adding targets.
Simplify PathInfo setup.
Modify single-target-intrinsic.slang - it no longer failed because there were no longer multiple definitions for the same target.
