Add `core/list-item` to the block attributes supported by block bindings so its `content` rich text can be bound, and cover the basic (non-nested) case in the render tests.

This is a clean enablement with no render-side changes. A List Item that contains a nested List keeps both inside the same `<li>`; preserving that nested list when `content` is bound is handled separately by the `WP_Block::replace_html()` inner-block fix.

…locks.

The `wp_get_elements_class_name()` function previously generated CSS class names by hashing the serialized block data via `md5()`. Identical blocks received the same `wp-elements-*` class name and the Style Engine deduplicated their CSS rules into one, causing a parent block's element style (e.g. link color) to cascade down and override a child block's identical style due to CSS source order.

The function is updated to use `wp_unique_prefixed_id()` instead, generating sequential unique class names (`wp-elements-1`, `wp-elements-2`, etc.) that match the block editor's JavaScript implementation. The now-unused `$parsed_block` parameter is removed from the function signature.

PHPStan rule level 10 errors are also resolved in the related code. See #64898.

Adds gray WordPress logo image files (`w-logo-gray-white-bg.png` and `w-logo-gray-white-bg.svg`) to `wp-includes/images/`, and updates `the_embed_site_title()` and `do_favicon()` to use the new images as the fallback site icon, maintaining visual consistency with the login screen logo updated in r61989.

Replaces CSS custom property references for focus styles in the embed template (`--wp-admin-theme-color` and `--wp-admin-border-width-focus`) with their literal values, as these admin-theme variables are not defined in the oEmbed template context.
