bootstrap: use different scripts to setup different configurations

This patch splits the handling of isMainThread and
ownsProcessState from conditionals in
lib/internal/bootstrap/node.js into different scripts under
lib/internal/bootstrap/switches/, and call them accordingly
from C++ after node.js is run.

This:

  • Creates a common denominator of the main thread and the worker
    thread bootstrap that can be snapshotted and shared by
    both.
  • Makes it possible to override the configurations on-the-fly.
Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • documentation is changed or added
  • commit message follows commit guidelines

nit: i think if we decide we really need/want to separate these out, we should stick to more straight-forward filenames for them, such as is_main_thread.js/is_not_main_thread.js and owns_process_state.js/not_owns_process_state.js instead of simply true.js/false.js.

@joyeecheung The C++ linter is failing due to some long lines.

This patch splits the handling of `isMainThread` and
`ownsProcessState` from conditionals in
`lib/internal/bootstrap/node.js` into different scripts under
`lib/internal/bootstrap/switches/`, and call them accordingly
from C++ after `node.js` is run.

This:

- Creates a common denominator of the main thread and the worker
  thread bootstrap that can be snapshotted and shared by
  both.
- Makes it possible to override the configurations on-the-fly.

Still just one remaining C++ lint failure:

07:10:11 File "src/node.cc" does not use "Boolean"

Oops, sorry, I no longer run the linter locally ever since there's #29918 ..
