deps: update v8.gyp and run Torque

Synchronize source files list with upstream's BUILD.gn.

Teach v8.gyp to build and run torque, V8's DSL for generating builtins.

On Windows, the torque binary needs to be compiled and linked
with exception semantics and assume V8 is embedded.

Fixes: nodejs/node-v8#57
