Before this commit it was using a tagged union to store the one-byte and
two-byte pointers.

From a `sizeof(UnionBytes)` perspective that makes no difference - there
is a hole between the tag and the union - and it makes the code just a
little harder to reason about, IMO.

This patch splits `NativeModuleLoader` into two parts - a singleton
that only relies on v8 and `node::Mutex` and a proxy class for
the singleton (`NativeModuleEnv`) that provides limited access to
the singleton as well as C++ bindings for the Node.js binary.
`NativeModuleLoader` is then no longer aware of `Environment`.

<title>process: specialize building and storage of process.config</title>

Instead of treating config.gypi as a JavaScript file, specialize
the processing in js2c and make the serialized result a real JSON
string (with 'true' and 'false' converted to boolean values) so
we don't have to use a custom deserializer during bootstrap.

In addition, store the JSON string separately in NativeModuleLoader,
and keep it separate from the map of the builtin source code, so
we don't have to put it onto `NativeModule._source` and delete it
later, though we still preserve it in `process.binding('natives')`,
which we don't use anymore.

This patch also makes the map of builtin source code and the
config.gypi string available through side-effect-free getters
in C++.

<title>src: use STL containers instead of v8 values for static module data</title>

Instead of putting the source code and the cache in v8::Objects,
put them in per-process std::maps. This has the following benefits:

- It's slightly lighter in weight compared to storing things on the
  v8 heap. Also it may be slightly faster since the preivous v8::Object
  is already in dictionary mode - though the difference is very small
  given the number of native modules is limited.
- The source and code cache generation templates are now much simpler
  since they just initialize static arrays and manipulate STL
  constructs.
- The static native module data can be accessed independently of any
  Environment or Isolate, and it's easy to look them up from the
  C++'s side.
- It's now impossible to mutate the source code used to compile
  native modules from the JS land since it's completely separate
  from the v8 heap. We can still get the constant strings from
  process.binding('natives') but that's all.

A few drive-by fixes:

- Remove DecorateErrorStack in LookupAndCompile - We don't need to
  capture the exception to decorate when we encounter
  errors during native module compilation, as those errors should be
  syntax errors and v8 is able to decorate them well. We use
  CompileFunctionInContext so there is no need to worry about
  wrappers either.
- The code cache could be rejected when node is started with v8 flags.
  Instead of aborting in that case, simply keep a record in the
  native_module_without_cache set.
- Refactor js2c.py a bit, reduce code duplication and inline Render()
  to make the one-byte/two-byte special treatment easier to read.
