src: refactor uncaught exception handling
The C++ land `node::FatalException()` is not in fact fatal anymore.
It gives the user a chance to handle the uncaught exception
globally by listening to the `uncaughtException` event. This patch
renames it to `TriggerUncaughtException` in C++ to avoid the confusion.

In addition rename the JS land handler to `onGlobalUncaughtException`
to reflect its purpose - we have to keep the alias
`process._fatalException` and use that for now since it has been
monkey-patchable in the user land.

This patch also

- Adds more comments to the global uncaught exception handling routine
- Puts a few other C++ error handling functions into the `errors`
  namespace
- Moves error-handling-related bindings to the `errors` binding.

cde3928a10 process: improve queueMicrotask performance
Optimize the hot code paths of queueMicrotask by
not creating unnecessary objects, not looking up
properties on frozen primordials, etc.

abf765e33c process: code cleanup for nextTick
Fix a few edge cases and non-obvious issues with nextTick:
1. Emit destroy hook in a try-finally rather than triggering
it before the callback runs.
2. Re-word comment for processPromiseRejections and make sure
it returns true in the rejectionHandled case too.
3. Small readability improvements.

f4f937b296 lib: remove Reflect.apply where appropriate
Using Reflect.apply where the callback context does not need
to change is unnecessary and less performant.

process: reduce the number of internal frames in async stack trace
Previously, we call the JS land `runNextTicks` implementation
immediately from JS land after evaluating the main module or the
input, so these synchronous JS call frames would show up in the stack
trace of the async errors, which can be confusing. This patch moves
those calls into C++ so that more of these internal scheduler
implementation details can be hidden and the users can see a cleaner
a cleaner async JS stack trace.

process: add --unhandled-rejections flag
This adds a flag to define the default behavior for unhandled
rejections. Three modes exist: `none`, `warn` and `strict`. The first
is going to silence all unhandled rejection warnings. The second
behaves identical to the current default with the excetion that no
deprecation warning will be printed and the last is going to throw
an error for each unhandled rejection, just as regular exceptions do.
It is possible to intercept those with the `uncaughtException` hook
as with all other exceptions as well.

This PR has no influence on the existing `unhandledRejection` hook.
If that is used, it will continue to function as before.

112cc7c275 lib: use safe methods from primordials
This changes the primordials to expose built-in prototypes with their
methods already uncurried.
The uncurryThis function is therefore moved to the primordials.
All uses of uncurryThis on built-ins are changed to import the relevant
prototypes from primordials.
All uses of Function.call.bind are also changed to use primordials.

8d669bbeb1 process: refactor global.queueMicrotask()
- Lazy load `async_hooks` in the implementation
- Rename `process/next_tick.js` to `process/task_queues.js`
  and move the implementation of `global.queueMicrotask()`
  there since these methods are conceptually related to
  each other.
- Move the bindings used by `global.queueMicrotask()` into
  `node_task_queue.cc` instead of the generic `node_util.cc`
- Use `defineOperation` to define `global.queueMicrotask()`
