Felix Arntz 56b5244fdb Media: Enhance wp_get_loading_optimization_attributes() to support arbitrary context values.
The `wp_get_loading_optimization_attributes()` function, which was introduced in 6.3, based on the now deprecated `wp_get_loading_attr_default()` function introduced in 5.5, relies on a `$context` parameter based on which it may alter its behavior and the attributes returned. So far, it has only supported context values used within WordPress core.

This changeset decouples the behaviors of the function from specific contexts, allowing for more flexibility. Theme and plugin developers will be able to rely on their own context values when rendering images in non-standard ways, rather than being forced to use a core context, to get the loading optimization benefits the function provides.

As part of this change, a `wp_loading_optimization_force_header_contexts` filter is introduced, which allows filtering the map of context values and whether they should be considered header contexts, i.e. i.e. any image having one of these contexts will be assumed to appear above the fold.
