feat(process): add process.{stdin, stdout, stderr} support (#1495)

* fix(stream): get Duplex working

* feat(process): add stdin,stdout,stderr in a semi-broken state (pipes??)

* test(NodeTestHelpers): fix test names

* test(NodeTestHelpers): add test for createDoneDotAll done called w error

* test(NodeTestHelpers): remove stray console.log

* fix(stream): fix bug in Duplex, Readable

* test(process.stdio): rename test

* fix(process.stdio): change onData listener to onReadable

* refactor(streams): add file-wide debug fn, destructure opts

* fix(child_process): check isCallable on promise

* fix: get stdio streams mostly working (mostly)

* fix(child_process): wait until stream is drained before calling end?

* fix(child_process): change to result?.then

* debug(child_process,streams): add EE id tracking, add shim for stdio after handle is dead

* test(child_process): fix double pipe test, temp fix for ChildProcess.kill() return val

* fix(child_process): remove immediate emit of exit on kill

* debug(streams): add more debug log

* debug(streams): add more debug logs part 2

* feat(streams,fs): add NativeWritable, adapt fs.WriteStream and fs.ReadStream to native
