[Feature] get where "exit" was called/shutdown started

Description

There currently is no simple way to figure out what/where exit was called.

Since PHP 8.4 PHP is a proper function, however it seems it's xdebug won't break on it, even if set (besides the fact, there's tons of bugs with IDEs/xdebug when breaking on built-in functions, e.g. defined()

Stepping through the code until exit; is reached isn't feasible in all cases (it happens in a long running process, this might take a day...)

It would be great if there were a magic constant similar to __COMPILER_HALT_OFFSET__ that is available in shutdown function callbacks, which includes the last executed file + line in the main thread before shutdown started. But that's just a simple first suggestion, I'm open to everything that makes identifying/debugging this easier.

この issue では、ファイル、テスト、実装のエントリポイントが指定されていません。まず PHP インタープリターで exit 関数および shutdown 関数のコールバックがどのように処理されるかを追跡し、次に最後に実行されたファイルと行を公開する実現可能な方法を定義してください。完了条件は、動作が仕様化され、実装され、テストでカバーされていることです。
