Move early-init.el to init.el (for now)

Browse source 
Calling tool-bar-mode, menu-bar-mode or scroll-bar-mode from
early-init.el seems to cause a 15-30% slowdown in startup time, possibly
for loading the UI libraries early.

Also, loading early-init.el eagerly from init.el causes a GC hit for
Emacs 25/26 users. It's too early to use this optimization.
