Xcode has no way pass env variables to react-native server

See original GitHub issue

Description:

To start react-native server XCode has to run:

launchPackager.command which starts new terminal emulator window
which runs packager.sh, this process as it runs in new terminal has no access to environment variables
to pass variables .packager.env file is created by XCode build script
.packager.env was sourced before starting react-native server https://github.com/facebook/react-native/commit/9ece5bda9bd035c31c3b975d1a8b66574dd43c4e#diff-fe2ea122979e8bb9729dff893828ae61L14

Our use case is to pass a path to another NODE_BINARY as we want to run exact version with help of nodenv (or nvm).

It seems that before https://github.com/facebook/react-native/commit/9ece5bda9bd035c31c3b975d1a8b66574dd43c4e#diff-fe2ea122979e8bb9729dff893828ae61L14 we could just pass NODE_BINARY to .packager.env.

My assumtion is that RCT_METRO_PORT is now ignored and thus port cannot be customized.
