[webkit-dev] Is UseV8.cmake still used?

[Kentaro Hara]

EFL and other ports used to have an option to build with V8, but it
looks like the option is no longer supported. For example, UseV8.cmake
is already out of sync with existing V8 binding files.

- Would it be OK to remove UseV8.cmake?

- Would it be OK to remove #if PLATFORM(CHROMIUM) from all V8 binding files?

If anyone has a plan to support the option in the near future, I'll
keep them as is.
