Create a new tf.env() getter that returns the global ENV

[nsthorat]

This is for the no exported objects rule which is against ES2015 module semantics.

This will be a replacement for anyone using tf.ENV as a global getter (we will not remove tf.ENV until the next major version bump).

We won't use exports = {} because it breaks the OSS build.

exports = {};

this is something we now do in the sync script internally? Revert here?

add jsdoc and export it in globals.ts so it shows up in our API docs

export function environment() {

how about making it shorter: tf.env() -- still clear what it returns.

Also can you file a bug and assign to this project https://github.com/tensorflow/tfjs/projects/10 which tracks 2.0
