Feature/loader build time comparison

[The-Only-Matrix]

This option gives you per loader module count, module time to execute, time comparison
with previous build of each loader. It stores current and previous build info in the file path given by user and it also allows user to commit the file containing build info into git version control system. But user can see the output of all builds in the terminal only.

Usage :-

const smp = new SpeedMeasurePlugin({
  compareLoadersBuild: { filePath: "./buildInfo.json", commitBuildInfo: true },
});

awesome stuff @The-Only-Matrix :D This looks great, thanks for raising it

I have a concern about the part of this PR where we git push etc., it feels like it's overstepping the boundaries of this plugin.

What do you think about keeping the output formatting of this PR (which is great), and just removing the part that automates the committing and pushing of the generated file? I think we could make it a lot more flexible to peoples' use-cases by just adding some docs on how to do the same thing themselves with some documentation/code-snippets of a Husky/Travis setup or something.
