stats.json are too big

[VladimirPal]

Hi!
my stat.json is over 100 mb(vendor.js over 15mb), why you cache it?
I have multiple entries with multiple Html output files. Each change causes read stats.json for each Html file just to inject links, it works dramatically slow.

I've reduced stats.json - now it's 17K

statsFromBuild.toJson({
  all: false,
  assets: true,
  entrypoints: true,
});
