Refresh of Remote Debugging

High level changes:
- `<div class="screenshot">` --> `<figure>`
- `<div class="collapsible">` --> `<section class="collapsible">`
- other HTML cleanup
- changed any references to `about:chrome` to `chrome://inspect` (also, wrapped in bold tags instead of code tags)

For **remote-debugging.html**:
- many changes so best to actually preview the page instead of looking at diff
- cleaned up text to incorporate debugging Android WebViews better
- added new images/screenshots, clarified some screenshots with callouts, deleted unused screenshots
- created "Additional information about ADB" and "Remote debugging for DevTools extension developers" sections at bottom to move less viewed (my assumption) content out of the way




I've got v35... Regardless: updated!
