Implement inline install UI for views.

To make this easier, the extension install dialog was changed from doing layout
by hand to using GridLayout (thus no longer necessitating overrides of
GetPreferredSize/Layout or lots of math).

To lessen the repeated logic between the inline install UIs,
ExtensionInstallUI::Prompt was beefed up to return formatted data directly
(and in the case of rating stars, include the logic for which ones to show).

Also includes some other tweaks:
- Rename inline install dialog to "Add to Chrome" and the install button in it
  to "Add"
- Use the final webstore JSON data URLs
