refactor: change zend_is_true to return bool (#14301)
Previously this returned `int`. Many functions actually take advantage of the fact this returns exactly 0 or 1. For instance, `main/streams/xp_socket.c` does: sockopts |= STREAM_SOCKOP_IPV6_V6ONLY_ENABLED * zend_is_true(tmpzval); And `Zend/zend_compile.c` does: child = &ast->child[2 - zend_is_true(zend_ast_get_zval(ast->child[0]))]; I changed a few places trivially from `int` to `bool`, but there are still many places such as the object handlers which return `int` that should eventually be `bool`.

* zend_is_true now returns bool rather than int. Note that on PHP 8 this has

always returned 0 or 1, so conversion should be trivial.
