This change allows all boolean flags to be negated using the `--no-`
prefix.
Flags that are `true` by default (for example `--deprecation`) are
still documented as negations.
With this change, it becomes possible to easily flip the default
value of a boolean flag and to override the value of a flag passed
in the NODE_OPTIONS environment variable.
`process.allowedNodeEnvironmentFlags` contains both the negated and
non-negated versions of boolean flags.

The connection between the JS land zero fill toggle and the

I added it in commit 57231d5286 ("src: notify V8 profiler when we're
idle") from October 2013 as a stop-gap measure to measure CPU time
rather than wall clock time, otherwise processes that spend a lot
of time sleeping in system calls give a false impression of being
very busy.
That fix is not without drawbacks because the idle flag is set before
libuv makes I/O callbacks and cleared again after. I/O callbacks can
result into calls into JS code and executing JS code is as non-idle
as you can get.
In commit 96ffcb9a21 ("src: reduce cpu profiler overhead") from January
2015, I made Node.js block off the SIGPROF signal that V8's CPU profiler
uses before Node.js goes to sleep. The goal of that commit is to reduce
the overhead from EINTR system call wakeups but it also has the pleasant
side effect of fixing what the idle notifier tried to fix.
This commit removes the idle notifier and turns the JS process object
methods into no-ops.

Enable JS wrapper objects to be used as transferable or cloneable
objects in `postMessage()` calls, by having them extend a C++-backed
class.
This requires a few internal changes:
- This commit adds the possibility for transferred objects to
read/write JS values at the end of the serialization/deserialization
phases.
- This commit adds the possibility for transferred objects to list
sub-transferables, e.g. typically the public JS wrapper class
would list its C++ handle in there.
- This commit adds usage of `BaseObject` in a few more places, because
now during deserialization weakly held objects can also be involved,
in addition to `MessagePort`s.
