For the initial iteration, only the default resolver can be
serialized/deserialized. If `dns.setServers()` has been
called, we'll preserve the configured DNS servers in the snapshot.
We can consider exposing the serialization method if it becomes
necessary for user-land snapshots.

Instead of creating an object template for every ContextifyContext,
we now create one object template that can be reused by all
contexts. The native pointer can be obtained through an embdder
pointer field in the creation context of the receiver in the
interceptors, because the interceptors are only meant to be invoked
on the global object of the contextified contexts. This makes
the ContextifyContext template context-independent and therefore
snapshotable.

The term "native module" dates back to some of the oldest code
in the code base. Within the context of Node.js core it usually
refers to modules that are native to Node.js (e.g. fs, http),
but it can cause confusion for people who don't work on this
part of the code base, as "native module" can also refer to
native addons - which is even the case in some of the API
docs and error messages.
This patch tries to make the usage of these terms more consistent.
Now within the context of Node.js core:
- JavaScript scripts that are built-in to Node.js are now referred
to as "built-in(s)". If they are available as modules,
they can also be referred to as "built-in module(s)".
- Dynamically-linked shared objects that are loaded into
the Node.js processes are referred to as "addons".
We will try to avoid using the term "native modules" because it could
be ambiguous.
Changes in this patch:
File names:
- node_native_module.h -> node_builtins.h,
- node_native_module.cc -> node_builtins.cc
C++ binding names:
- `native_module` -> `builtins`
`node::Environment`:
- `native_modules_without_cache` -> `builtins_without_cache`
- `native_modules_with_cache` -> `builtins_with_cache`
- `native_modules_in_snapshot` -> `builtins_in_cache`
- `native_module_require` -> `builtin_module_require`
`node::EnvSerializeInfo`:
- `native_modules` -> `builtins
`node::native_module::NativeModuleLoader`:
- `native_module` namespace -> `builtins` namespace
- `NativeModuleLoader` -> `BuiltinLoader`
- `NativeModuleRecordMap` -> `BuiltinSourceMap`
- `NativeModuleCacheMap` -> `BuiltinCodeCacheMap`
- `ModuleIds` -> `BuiltinIds`
- `ModuleCategories` -> `BuiltinCategories`
- `LoadBuiltinModuleSource` -> `LoadBuiltinSource`
`loader.js`:
- `NativeModule` -> `BuiltinModule` (the `NativeModule` name used in
`process.moduleLoadList` is kept for compatibility)
And other clarifications in the documentation and comments.

This adds a --build-snapshot runtime option which is currently only
supported by the node_mksnapshot binary, and a --node-snapshot-main
configure option that makes use it to run a custom script when
building the embedded snapshot. The idea is to have this experimental
feature in core as a configure-time feature for now, and investigate
the renaming V8 bugs before we make it available to more users via
making it a runtime option.

Put the hrtime backing store in the process methods binding data
so that it can be integrated into the snapshot builder. For
now we simply discard the contents of the hrtime buffer during
serialization and create new buffers upon deserialization because
the contents are only useful in a synchronous call.
This also moves the helper function for creating V8 FastAPI methods
into `Environment::SetFastMethod()` for code reuse. The v8::CFunction
need to be created before the Environment is created so that we
have the CTypeInfo address available for external reference
registration.

Add an ExternalReferenceRegistry class for registering static
external references.
To register the external JS to C++ references created in a binding
(e.g. when a FunctionTemplate is created):
- Add the binding name (same as the id used for `internalBinding()`
and `NODE_MODULE_CONTEXT_AWARE_INTERNAL`) to
`EXTERNAL_REFERENCE_BINDING_LIST` in `src/node_external_reference.h`.
- In the file where the binding is implemented, create a registration
function to register the static C++ references (e.g. the C++
functions in `v8::FunctionCallback` associated with the function
templates), like this:
```c++
void RegisterExternalReferences(
ExternalReferenceRegistry* registry) {
registry->Register(cpp_func_1);
}
```
- At the end of the file where `NODE_MODULE_CONTEXT_AWARE_INTERNAL` is
also usually called, register the registration function with
```
NODE_MODULE_EXTERNAL_REFERENCE(binding_name,
RegisterExternalReferences);
```
