Remove obsolete code from gr-diff-selection

Because of this check in `handleCopy` we never actually deal with copy
events originating from comments:
`if (!descendedFromClass(target, 'diff-row', this.diffTable)) return;`

Comment thread elements are slotted, so they don't "descend" from diff
rows. So all the code that I am removing is just dead code at the
moment.

There is also no good reason for having a dedicated copy handler for
copying content from comment widgets. This works fine out of the box.
The `user-select` css rules already accomplish what we need in terms
of ignoring comments or code depending on where you start your
selection.
