Embedders may want to control whether a Node.js instance
controls the current process, similar to what we currently
have with `Worker`s.
Previously, the `isMainThread` flag had a bit of a double usage,
both for indicating whether we are (not) running a Worker and
whether we can modify per-process state.

So that it's easier to tell whether we are manipulating per-process
global states that may need to be treated with care to avoid races.
Also added comments about these variables and moved some of them
to a more suitable compilation unit:
- Move `v8_initialized` to `util.h` since it's only used in
`util.cc` and `node.cc`
- Rename `process_mutex` to `tty_mutex` and move it into
`node_errors.cc` since that's the only place it's used
to guard the tty.
- Move `per_process_opts_mutex` and `per_process_opts`
into `node_options.h` and rename them to
`per_process::cli_options[_mutex]`
- Rename `node_isolate[_mutex]` to `per_process::main_isolate[_mutex]`

Use `ToV8Value()` where appropriate to reduce duplication
and avoid extra `Array::Set()` calls.

Expose the POSIX credential accessors through
`internalBinding('credentials')` instead of setting them on the
process or bootstrapper object from C++ directly. Also moves
`SafeGetEnv` from `internalBinding('util')` to
`internalBinding('credentials')` since it's closely related to
the credentials.
In the JS land, instead of wrapping the bindings then writing
to the process object directly in main_thread_only.js, return
the wrapped functions back to bootstrap/node.js where they get
written to the process object conditionally for clarity.
