For Vulkan-compliant codegen use 'tex_sampler' as variable name instead of reserved word 'sampler' as consistent with earlier changes in other shader libs.
Add a test to generate and validate Vulkan-compliant GLSL.
Fix bug that wasn't including codevalidator arguments as part of the codevalidator command.
