Refresh monitored specs, Add new specs (#286)

Moved to ignore list:
- Virtual scroller - no longer being considered

Moved to browser-specs list:
- Open Screen Protocol - published as FPWD
- Sanitizer API - behind a flag in Firefox, in development in Chrome
- Scheduling APIs - spec filled out and origin trial in Chrome

Comment updated:
- Raw Sockets API - no clear implementation plan, harmful for Mozilla
- Conversion Measurement API - spec filled out but no clear implementation plan
- Manifest Incubations - spec filled out but Chromium specific
- App History - spec filled out but still early exploration
