Kévin Petit bec7e0393f Add all accepted target environments to the tools' help texts (#2687) ... Several tools take a --target-env option to specify the SPIR-V environment to use. They all use spvParseTargetEnv to parse the user-specified string and select the appropriate spv_target_env but all tools list only _some_ of the valid values in their help text. This change makes the help text construction automatic from the full list of valid values, establishing a single source of truth for the values printed in the help text. The new utility function added allows its user to specify padding and wrapping constraints so the produced strings fits well in the various help texts.
