Modify the native `SetImmediate()` functions to take generic C++
callables as arguments. This makes passing arguments to the callback
easier, and in particular, it allows passing `std::unique_ptr`s
directly, which in turn makes sure that the data they point to is
deleted if the `Environment` is torn down before the callback can run.

This patch moves the serialization of coverage profiles into
C++. With this we no longer need to patch `process.reallyExit`
and hook into the exit events, but instead hook into relevant
places in C++ which are safe from user manipulation. This also
makes the code easier to reuse for other types of profiles.

are always unconditionally enabled during bootstrap when

not use the performance timeline API to enable GC tracking.
This patch makes the callback addition conditional and only
enables them when the user explicitly requests
`observer.observe(['gc'])` to avoid the overhead.

Adds `TRACING_CATEGORY_NODE`, `TRACING_CATEGORY_NODE1` and
`TRACING_CATEGORY_NODE2` helper macros for consistently building
trace event category strings. For instance,
`TRACING_CATEGORY_NODE2(foo, bar)` would generate the category
string `node,node.foo,node.foo.bar`, such that...
```
TRACE_EVENT_NESTABLE_ASYNC_BEGIN0(
TRACING_CATEGORY_NODE2(foo, bar),
"baz", 1);
```
Would emit if trace events are enabled for categories: `node`,
`node.foo`, or `node.foo.bar`.
This allows a natural scoping down of what trace events a user
may want to receive. Enabling the `node` category would receive
everything Node.js produces.
