Database: Replace str_ends_with() usage in wpdb::prepare().

Browse Source 
This avoids a fatal error if the file is included directly outside of WordPress core, e.g. by HyperDB.

While WordPress core does include a polyfill function, it is not directly loaded in the `wpdb` class.

This commit replaces the `str_ends_with()` calls with `substr_compare()` for now.

Follow-up to [55151].

Props Otto42.
See #52506.
