No #line directives generated when --target-env is vulkan1.1, vulkan1.2 or vulkan1.3

[TonyBarbour]

GPU-AV depends on #line directives to determine which source line is responsible for a validation error. glslang is generating #line directive(s) with --target-env vulkan1.0, but not vulkan1.1, 1.2, or 1.3. #line is also created when no --target-env is specified. Issue is at https://github.com/KhronosGroup/Vulkan-ValidationLayers/issues/5596

We have the same problem in LightweightVK when using glslang C-interface. No SPIR-V OpSource is generated when emit_nonsemantic_shader_debug_source is enabled.

@corporateshark I think that is a somewhat different issue, could you open a new issue for your problem? Also, could you confirm that you're using the most recent version of glslang as there was a somewhat similar sounding bug that was fixed recently.
