This change allows for easier recognition of builtin modules in stack
traces.

Previously `internal/bootstrap/pre_execution.js` requires
`internal/modules/cjs/loader.js` which in turn requires
`internal/bootstrap/pre_execution.js`. This patch moves the
entry point execution logic out of `pre_execution.js` and
puts it into `internal/modules/run_main.js`. It also tests
that `Module.runMain` can be monkey-patched before further
deprecation/refactoring can be done.
Also added an internal assertion `hasLoadedAnyUserCJSModule`
for documentation purposes.

This patch splits the execution mode selection from the environment
setup in `lib/internal/bootstrap/node.js`, and split the entry point
of different execution mode into main scripts under
`lib/internal/main`:
- `check_syntax.js`: used when `-c`/`--check` which only checks the
syntax of the input instead of executing it.
- `eval_stdin.js`: used when `-e` is passed without value and stdin
is not a TTY (e.g. something is piped).
- `eval_string`: used when `-e` is passed along with a string argument
- `inspect.js`: for `node inspect`/`node debug`
- `print_bash_completion.js`: for `--completion-bash`
- `print_help.js`: for `--help`
- `prof_process.js`: for `--prof-process`
- `repl.js`: for the REPL
- `run_main_module.js`: used when a main module is passed
- `run_third_party_main.js`: for the legacy `_third_party_main.js`
support
- `worker_thread.js`: for workers
This makes the entry points easier to navigate and paves the way
for customized v8 snapshots (that do not need to deserialize
execution mode setup) and better embedder APIs.
As an example, after this patch, for the most common case where
Node.js executes a user module as an entry point, it essentially
goes through:
- `lib/internal/per_context.js` to setup the v8 Context (which is
also run when setting up contexts for the `vm` module)
- `lib/internal/bootstrap/loaders.js` to set up internal binding
and builtin module loaders (that are separate from the loaders
accessible in the user land).
- `lib/internal/bootstrap/node.js`: to set up the rest of the
environment, including various globals and the process object
- `lib/internal/main/run_main_module.js`: which is selected from
C++ to prepare execution of the user module.
This patch also removes `NativeModuleLoader::CompileAndCall` and
exposes `NativeModuleLoader::LookupAndCompile` directly so that
we can handle syntax errors and runtime errors of bootstrap
scripts differently.

This patch refactors the branches for choosing the mode to run
Node.js in `internal/bootstrap/node.js`. Instead of inlining the
decision making all in `startup`, we create a `startExecution()`
function which either detects and start the non-user-code mode,
or prepares for user code execution (worker setup, preloading modules)
and starts user code execution.
We use early returns when we decide the mode to run Node.js in for fewer
indentations and better readability.
This patch also adds a few comments about the command-line switches
and a few TODOs to remove underscore properties on `process` that
are mainly used for bootstrap mode branching. It also includes
a few other refactoring such as inlining functions/variables
that are not reused and removing the default argument of
`evalScript` for better clarity.

1) Switched + / - and red / green in diffs. It seems like that style
is more natural to most people.
2) Short primitives do not use the diff anymore. Especially short
numbers can be read well like 1 !== 2. Cases that can not be
displayed like that (e.g., -0 and +0) use the regular diff output.
3) Improved error descriptions. It was not always clear what the
messages stood for. That should now be resolved.
4) Added a position indicator for single lines in case a tty is used
and the line is shorter than the visual columns.
5) Color detection is now done by checking stderr instead of stdout.

The file no longer works after the removal of the --debug/--debug-brk
switches in commit 47f8f74 ("src: remove support for --debug".)
This commit also removes several tests that still referenced the
old debugger but were either unit-testing its internals or passing
for the wrong reason (like expecting an operation to fail, which
it did because the debugger is gone.)

This commit improves module loading performance by at least ~25-35%
in the module-loader benchmarks.
Some optimization strategies include:
* Try-finally/try-catch isolation
* Replacing regular expressions with manual parsing
* Avoiding unnecessary string and array creation
* Avoiding constant recompilation of anonymous functions and
function definitions within functions

In dfee4e3712, the module wrapper
and line offset used when wrapping module code was changed to
better report errors on the first line of modules. However, that
commit did not update the runInThisContext() call used to
execute the core modules, so their error line numbers have been
off by one. This commit provides the correct lineOffset for core
modules.
