Remove all of ui/views, ui/aura/, ui/compositor, ui/ozone,
and a whole bunch of dead code.
This is part one of multiple patches. This removes the
toplevel directories, and some utility files. Further
patches will deep dive to do surgery on the build system,
the resource bundles, et cetera.

v8_inspector is a peer to web for now.
Eventually it should be its own separate target
and not depend on core or platform at all, but we can't yet.
This creates a place for us to move the debugger-inspector
code to so it can be refactored to not depend on core.
I also moved the public target for sky out of public/
and renamed it "engine" instead of blink.
