This adds a new handlebars helper {{amp_analytics}} which outputs the
GA configuration script if the amp_gtag_id setting is present.
We also update {{amp_components}} to output the GA script in the head if
the setting is present
The featured post images are distorted in the AMP template. This change adds `object-fit:cover` styling, and thus avoids distortion but allows images to scale.
Fixes#11560
