holoscan::ScopedWaitedFlock

RAII wrapper over a waited ScopedFlock.

At the initialization, it waits for the lock to be available until wait_time_ms_ ms is reached. It stops trying to lock after that and does not lock the file descriptor.

When wait time is set to zero or less, then it falls back to ScopedFlock
