Add to suite of MSL tests and references any existing GLSL tests that successfully convert GLSL->SPIRV->MSL and compile as MSL. test_shaders_helper() ignores hidden files that start with '.', to avoid accidentally finding hidden OSX files such as .DS_Store. Use xcrun to compile MSL shaders instead of hard-coded path to Metal compiler. Wrap calls to xcrun in exception handling to ignore if Xcode not installed. For MSL tests, move call to validate_shader_msl() to after call to regression_check() to allow a converted MSL shader to be saved for manual review even if it doesn't successfully compile as MSL.
