chore: replace lazy_static with std::sync::LazyLock (lance-format#4109)

This PR will replace lazy_static with std::sync::LazyLock.

lazy_static is known to compile more slowly and relies on macros, which
makes maintenance more difficult. Now that there is a new standard API
that can fully replace it, this change is appropriate.
