feat: change parking lot mutex to std mutex

[kemingy]

History: parking_lot used to be faster and smaller than the std mutex. But Rust 1.62 improved the std::sync::Mutex a lot.

Benefit:

This means that on platforms like Linux and Windows, the operating system will be responsible for managing the waiting queues of the locks, such that any kernel improvements and features like debugging facilities in this area are directly available for Rust programs.

One benefit of parking_lot: deadlock detection.

Some comparison:

• Mutex is slower than standard library's on Intel i9 and ARM CPUs Amanieu/parking_lot#338 may not be very reasonable

Loom has the std::sync::Mutex. For parking_lot, it seems we need to wrap it like tokio. Examples can be found in tokio repo.
