This new API lets clients request a minimal spv_target_env value that supports a given Vulkan and SPIR-V version, by a generic numbering scheme (as already defined by Vulkan and SPIR-V specs). This breaks a formal source dependency from Glslang to SPIRV-Tools. When a new API is rolled out, such as Vulkan 1.2, Glslang currently needs to reference a specific SPIRV-Tools enum by name.
