replace lazy_static with std's OnceLock

[Liyixin95]

The once_cell has been stable in std, and the 'lazy_static' is going to be deprecated, so it's better to use std's once_cell instead of lazy_static.

How about using LazyLock?

How about using LazyLock?

LazyLock is newly introduced to std in 1.80. So using LazyLock will bump the msrv up to 1.80.

How about using LazyLock?

There are three choice:

1. use OnceLock, which is little more verbose
2. use std's LazyLock, which will bump up the msrv
3. use the LazyLock in once_cell.

You maintainer can make a decision and I will follow.

Thanks very much for your contribution!
I think that using OnceLock seems really a little verbose, so maybe we can use LazyLock and bump the MSRV?
Bumping MSRV is not considered as a breaking change.
