Subject: Start supporting chrome.resourcesPrivate API

- Register browser interface binders for PDF viewer. Copied back this
logic from the guest view implementation (from dev) to enable usage
of chrome.resourcesPrivate API in the PDF viewer of 5.15.
- Implement template replacements for extensions. Replace i18n
placeholders in the PDF viewer HTML to prevent syntax issues and
support localization.

Task-number: QTBUG-90035
