GN: build Lua tools when skia_use_lua.
When we opt into Lua, this builds SampleLua into SampleApp, and the lua_app and lua_pictures tools.
I've tested this builds with and without skia_use_system_lua on my Mac laptop and Linux desktop.
I've made lua_pictures.cpp's flags static to avoid conflicts with flags in SkCommonFlags.cpp.
