commit 054b56e5e39800e6c99121da4d42b61727bd67fc
Author: Stuart Langley <slangley@chromium.org>

Remove WebNonCopyable and replace any usage with explicit "= delete".

In the few use cases that were using WebNonCopyable I followed the Google
C++ style guide, which explicitly states that to remove copy
operations "explicitly disable them using = delete in the public: section".
https://google.github.io/styleguide/cppguide.html#Copyable_Movable_Types

Most places were just including the header file without actually using
the type.

This CL contains no logic changes.
