inspector: introduce the `--inspect-wait` flag

This PR introduces the --inspect-wait flag, which allows debugger to wait for attachement. This flag is useful when you want to debug the code from the beginning. Unlike --inspect-brk, which breaks on the first line, this flag waits for debugger to be connected and then runs the code as soon as a session is established.

It's designed to simplify debugging by removing the need for manual intervention and providing a smoother debugging experience. With support for breaking on the first line and automatic process resumption, it streamlines the debugging process.
