php_embed_ub_write() never decrements remaining when php_embed_single_write() returns 0, so if php_handle_aborted_connection() doesn't actually abort (e.g. ignore_user_abort=1), the write loop spins forever. sapi_cgi_ub_write() already returns str_length - remaining in this same situation, so this makes php_embed_ub_write() do the same.

Fixes #23423
