Felix Arntz a56a83fc6c Media: Increase default for wp_omit_loading_attr_threshold to 3.
The previous default threshold for how many content images to skip lazy-loading on (which was just 1) has proven to be too strict: HTTP Archive data shows that >70% of sites have up to 3 equal-sized images in the initial viewport, each of which could be the LCP image and therefore should not be lazy-loaded. Lazy-loading too many images has adverse effects on load time performance, while increasing the default threshold will not negatively affect load time performance even for sites where a threshold of 1 would be the perfect choice.

The change of default value in this changeset will improve performance for more WordPress sites out of the box. The `wp_omit_loading_attr_threshold` filter can still be used to customize and fine tune the value where needed.

Props thekt12, spacedmonkey, westonruter, flixos90.
Fixes #58213.
