WP oEmbed: Filter entire logo markup to allow inline svg, objects, et al.

[peterwilsoncc]

The logo markup in wp-includes/embed-template.php includes an image tag.

printf(
        '<a href="%s" target="_top"><img src="%s" srcset="%s 2x" width="32" height="32" alt="" class="wp-embed-site-icon"/><span>%s</span></a>',
        esc_url( home_url() ),
        esc_url( get_site_icon_url( 32, admin_url( 'images/w-logo-blue.png' ) ) ),
        esc_url( get_site_icon_url( 64, admin_url( 'images/w-logo-blue.png' ) ) ),
        esc_html( get_bloginfo( 'name' ) )
);

It'd be grand if the entire markup could be filterable to allow for inline-svg, objects, plain text and other markup for the logo.

Filter name suggestions:

• embed_logo_markup
• embed_site_title

Shifting for review by others

Sounds reasonable to me. While working on #34561 I've added an embed_site_title filter to the patch there.

In 35578:

Embeds: Add a filter for the site title HTML.

Props swissspidy.

Fixes #34534.
