bootstrap: support more builtins in the embedded code cache
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.
