Upgrade to Glslang 11.0.0 (#1466)

* 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

* Upgrade slang-binaries to have new glslang.

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

* Small improvements to glslang building process documentation.
