Rollup merge of #124475 - GKFX:more-dependency-pruning, r=oli-obk

Remove direct dependencies on lazy_static, once_cell and byteorder

The relevant functionality of all three crates is now available and stable in the standard library, i.e. `std::sync::OnceLock` and `{integer}::to_le_bytes`. I think waiting for `LazyLock` (#109736) would give marginally more concise code, but not by much.
