Optimize importing from @patternfly/react-tokens

Description of problem:
Sometimes builds fail because react-tokens import is so large it causes timeout errors. 

In many files we are importing from @patternfly/react-tokens using a format like:  

 import { something } from '@patternfly/react-tokens'  

Whenever we do that webpack has to parse 12k different token files. This caused a build failure in recent PF latest smoketesting.  It also increases build time.   It's much better to import a specific file, like: 

import something from '@patternfly/react-tokens/dist/esm/something'
