Unless configured, V8 defaults to limiting the max heaps size to 700 MB
or 1400MB on 32 and 64-bit platforms respectively. This default is
based on the browser use-cases and doesn't make a lot of sense
generally. This change properly configures the heap size based on
actual available memory.

- Assign thread IDs to `Environment` instances, rather than Workers.
This is more embedder-friendly than the current system, in which
all “main threads” (if there are multiple ones) would get the
id `0`.
- Because that means that `isMainThread === (threadId === 0)` no longer
holds, refactor `isMainThread` into a separate entity. Implement it
in a way that allows for future extensibility, because we use
`isMainThread` in multiple different ways (determining whether there
is a parent thread; determining whether the current thread has control
of the current process; etc.).

This patch moves most of the public C++ APIs into src/api/*.cc
so that it's easier to tell that we need to be careful about
the compatibility of these code.
Some APIs, like `node::LoadEnvironmet()`, `node::Start()` and
`node::Init()` still stay in `node.cc` because they are still
very specific to our use cases and do not work quite well yet
for embedders anyway - we could not even manage to write cctest for
them at the moment.
