It turns out that even with startup snapshots, there is a non-trivial
overhead for loading internal modules. This patch makes the loading
of the non-essential modules lazy again.
Caveat: we have to make some of the globals lazily-loaded too,
so the WPT runner is updated to test what the state of the global
scope is after the globals are accessed (and replaced with the
loaded value).

V8 already parses the source map magic comments. Currently, only scripts
and functions expose the parsed source map URLs. It is unnecessary to
parse the source map magic comments again when the parsed information is
available.

This patch refactors the DNS default resolver code to make it
easier to be included in a snapshot:
- The code specific for the callback-based DNS resolver are not
in a separate module to make the dependency clearer (it's not
actually needed if the user only ever loads `dns/promises`)
- The common part of the callback-based resolver and the promise-
based resolver is now ResolverBase. The other two user-facing
resolvers are now subclasses of ResolverBase. The default
Resolver is constructed with just ResolverBase. This would
be fine as the default resolver is never actually exposed
to the user-land and it has been working using duck-typing anyway.
- Move the construction of Resolver subclasses into a common
method `createResolverClass()` to reduce code duplication.
The two subclasses now also share the same base constructor.
This would make it possible for them to also share code
for snapshot support later.
- `--dns-result-order` is now queried and refreshed during
pre-execution. To avoid loading the cares_wrap binding unnecessarily
the loading of the binding is also made lazy.

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 patch:
- Make NativeModuleLoader::LookupAndCompile() detect parameters based
on module IDs. This allows us to compile more builtins when
generating the embedded bootstrap, including
- internal/per_context/*
- internal/bootstrap/*
- internal/main/*
- Move pre_execution.js to lib/internal/process as it needs to be
compiled as a regular built-in module, unlike other scripts
in lib/internal/bootstrap
- Move markBootstrapComplete() to the performance binding instead of
making it a function-wrapper-based global to reduce number of
special cases.
