Tiled Gallery Block: Images don't follow the "jetpack_photon_skip_image" filter

### Impacted plugin

Jetpack

### Quick summary

The Tiled Gallery Block always uses Proton CDN images, and there is no way to disable this. While the `jetpack_photon_skip_image` filter can be used to disable Photon for individual images, it is not applied in the Tiled Gallery Block.

This causes issues for individual images that need to be served directly from the site, for example, protected images.

### Steps to reproduce

1. Add the filter to skip all photon images `add_filter( 'jetpack_photon_skip_image', '__return_true' );` (easier for testing, in a real case scenario we won't skip all images).
2. Add the Tiled Gallery Block.
3. Images are served through Photon.

### If a workaround is available, please outline it here.

### Platform (Simple and/or Atomic)

_No response_

Start by reproducing the filter behavior with the Tiled Gallery Block and trace how its images are generated and routed through Proton CDN. Done means the jetpack_photon_skip_image filter is honored for affected images, while images that do not skip Photon continue using the CDN.
