[TIMOB-27235] IOS: Having "DEBUG=*" flag causes the appc run node process to fail due to "Javascript heap out of memory"

Steps to reproduce:

1. Create a default classic app with the CLI using appc new. 2. Make sure the tiapp.xml has 8.2.0 SDK. I used 8.2.0.v2019071001261 & 8.1.0.v20190709083308. 3. From the terminal run DEBUG=* appc run -p ios -T simulator -l trace. I have used simulator here but I guess it does not matter.

Actual results:

1. With DEBUG=* flag we see a lot of babel logging as transpiling is always on and eventually the build fails due to node running out of heap memory causing Javascript heap out of memory. 2. This does not affect runs without DEBUG=* flag which, directly does not affect out tooling. But, this flag is useful for looking at additional logging which is frequently used by us while testing & development. 3. Building to an Android device/emulator is fine.

Expected results:

1. Build does not fail with Javascript heap out of memory when flag DEBUG=* is used.
