src: use thread defaults provided by v8::platform by tomgco · Pull Request #4243 · nodejs/node

By passing `const int thread_pool_size = 0` to `CreateDefaultPlatform`
we allow v8 to choose sensible defaults based on the currently online
processors.

Based on the conversation in nodejs#4243 this implements a way to increase
and decrease the size of the thread pool used in v8.

Currently v8 restricts the thread pool size to `kMaxThreadPoolSize`
which at this commit is (4). So it is only possible to
decrease the thread pool size at the time of this commit. However with
changes upstream this could change at a later date.
If set to 0 then v8 would choose an appropriate size of the thread pool
based on the number of online processors.
