refactor: bundle the browser and renderer process electron code (#18553)

* refactor: bundle the browser and renderer process electron code

* Bundles browser/init and renderer/init
  * Improves load performance of main process by ~40%
  * Improves load performance of renderer process by ~30%
* Prevents users from importing our "requiring" our internal logic such
as ipc-main-internal.  This makes those message buses safer as they are
less accessible, there is still some more work to be done though to lock
down those buses completely.
* The electron.asar file now only contains 2 files, as a future
improvement maybe we can use atom_natives to ship these two files
embedded in the binary
* This also removes our dependency on browserify which had some strange
edge cases that caused us to have to hack around require-order and
stopped us using certain ES6/7 features we should have been able to use
(async / await in some files in the sandboxed renderer init script)

TLDR: Things are faster and better :)

* fix: I really do not want to talk about it

* chore: add performance improvements from debugging

* fix: resolve the provided path so webpack thinks it is absolute

* chore: fixup per PR review

* fix: use webpacks ProvidePlugin to keep global, process and Buffer alive after deletion from global scope for use in internal code

* fix: bundle worker/init as well to make node-in-workers work

* chore: update wording as per feedback

* chore: make the timers hack work when yarn is not used
