Replace Expected Values form with static display and popover form

### Story ###
- https://www.pivotaltracker.com/story/show/63991566

### Notes ###
- replaced expected values section in patient builder with static display with the following features:
  - for checkboxes, only the checked populations appear, otherwise <code>None</code> is displayed
  - for EoC measures, all populations are displayed with numerical expected values displayed
  - for CV measures, the IPP behaves like checkboxes, the MSRPOPL behaves like EoC populations, and OBSERV has special behavior where updating MSRPOPL re-renders the popover with the changed value of OBSERV fields
- removed empty population title header from patient builder population logic view template
