Implement one consistent table style across the site

[melwoodard]

The USWDS bordered table style should be used across vets.gov. This affects:

• GIBCT Institution detail page
  • [x] Benefits Calculator - table with $ totals
  • [x] School Summary
  • [x] Historical School Information
• Survivors and Dependents' Assistance
  • [x] Compare DEA and Fry Scholarship Benefits table
• Employer Commitments
  • [x] Commitments table

Update: I'll fix this issue and https://github.com/department-of-veterans-affairs/vets-website/issues/2693 across the various apps

I did some investigating today and found out that the usage of Foundation in the va_common is clobbering a lot of the USDS styles. My plan of attack is to break out Foundation so that we can import Foundation styles selectively (and remove/comment out ones we don't need, e.g. tables). I'll publish a new version of the gem with those changes and then upgrade all of our existing apps.

va_common has been updated and published—there are a couple PRs out in the wild across the various apps but once they are merged we should be good to go
