Reland: Further refine div output when a div receives focus

Reland: Further refine div output when a div receives focus

This cl makes div output the same way as classic:
- when a div receives either ChromeVox or page focus, read its text content or its aria label
- this cleans up output and retains the previously hardened behavior in Classic.

TEST=browse on a variety of sites like Gmail, Groups. Verify that despite bad markup, ChromeVox performs well and provides a smooth experience.
