build: create V8 code cache after script is run
This patch makes it possible to generate the code cache
for the builtins directly from the original script object
(instead of compiling a new one) and after the script has
been run (via `NativeModule.require`). Before this patch
only the top level functions (the wrapped ones)
are included in the cache, after this patch the inner
functions in those modules will be included as well.
Also blacklists modules from dependencies like V8 and
node-inspect since we cannot guarantee that they are suitable
to be executed directly.
