Summary: Compiling headless flipper takes a long time. This is because it individually compiles and bundles every plugin. When debugging core headless, you don't need to compile any plugins, so this adds a build flag `--no-plugins` to skip that and vastly speed up iteration speed. Reduces build time from 3 minutes to 20s Reviewed By: priteshrnandgaonkar Differential Revision: D16131322 fbshipit-source-id: 2b38ee37183a1257b3993f392cf623b2631fd7da
