enable lazy-loading of gitgraph.js (#9036)
- moved gitgraph.js to web_src and made it importable and es6-compatible - created new webpack chunk for gitgraph - enabled CSS loader in webpack - enabled async/await syntax via regenerator-runtime - added script to ensure webpack chunks are loaded correctly - disable terser's comment extraction to prevent .LICENCE files gitgraph.js has many issues: 1. it is incompatible with ES6 because of strict-mode violations 1. it does not export anything 1. it's css has weird styles like for `body` 1. it is not available on npm I fixed points 1-3 in our version so it's now loadable in webpack. We should eventually consider alternatives.lunny/display_deleted_branch2
