enable fast bundle when skip typecheck
enable fast bundle when skip typecheck

Use fast bundler if typecheck is skipped, assuming builders/developers
want to get result faster in such build config.

This will also remove the necessity of having devtools_fast_bundle
config from chromium CQ/CI's build.

This is step 6 of http://go/devtools-fast-bundle
