Alexandre Poirot 7f9229d43d Bug 1789201 - [devtools] Expose Services as a global to all DevTools modules. r=perftest-reviewers,nchevobbe,julienw,AlexandruIonescu
This will help transition to ES Modules as this symbol is exposed to them.

$ sed -ie "/require(.Services.)/d" $(git grep -l 'require("Services")' devtools/)
$ sed -ie "/loader.lazyRequireGetter(this, .Services./d" $(git grep -l 'loader.lazyRequireGetter(this, "Services"' devtools/)
+ the edition of builtin-modules.js + eslintrc.js
+ manual eslint fixes
+ removal of devtools-services in the debugger, except for jest tests
