Media: Enhance logic to determine LCP image in block themes and avoid lazy-loading it.

[52065] originally introduced the logic to guess the LCP image based on certain heuristics and to not lazy-load that image. However, with the introduction of block themes, that logic was not functioning correctly, resulting in all featured images to be lazy-loaded, regardless of whether it was the LCP image or not.

Together with an update to the core/post-featured-image block included in [55079], this changeset fixes the logic to correctly handle featured images in block themes as well.

Additionally, in combination with an update to the core/template-part block from [55246], this changeset includes an enhancement which uses the benefits of block template parts to avoid lazy-loading images in the header block template part, making the lazy-loading heuristics even more accurate for sites using a block theme.

Fixes #56930.
