Improve the serde impl for several types (`Lsn`, `TenantId`, `TimelineId`) by making them sensitive to `Serializer::is_human_readadable` (true for json, false for bincode). Fixes #3511 by: - Implement the custom serde for `Lsn` - Implement the custom serde for `Id` - Add the helper module `serde_as_u64` in `libs/utils/src/lsn.rs` - Remove the unnecessary attr `#[serde_as(as = "DisplayFromStr")]` in all possible structs Additionally some safekeeper types gained serde tests. --------- Co-authored-by: Joonas Koivunen <joonas@neon.tech>
