[BUG] - Compile Codex with GCC 14

[veaceslavdoina]

Describe the bug
Codex currently can't be compiled with GCC 14, which was released on Tue May 7 10:31:35 GMT 2024.

Based on the numbering scheme, this is a first v14 public release, 14.0 was used in the development process.

To Reproduce

1. Follow Building Codex guide
2. Install GCC 14
3. Run make update - ✅
4. Run make - ❌

Expected behavior
We should be able to compile Codex with GCC 14 and older versions as well.

Environment:

• OS: Ubuntu, Windows
• Version: latest
• Tag/Commit: master
• Arch: amd64

Additional context

• Workaround for CI on Windows was merged - Downgrade to gcc 13 on Windows #874

Work in progress - nim-codex/.gitmodules

• status-im/nim-bearssl - Update submodule
• vacp2p/nim-libp2p - https://github.com/vacp2p/nim-libp2p/tree/multihash-poseidon2
• nim-leopard - GCC-14 nim-leopard#15
• nim-codex-dht - GCC-14 nim-codex-dht#98
• nim-chronos - Update submodule
• nim-datastore
  • Tests for concurrent queries. Finishes disposed iterators. nim-datastore#67
  • Rename err to error to avoid naming conflict nim-datastore#68
  • Support GCC-14 nim-datastore#69
  • Skip unnecessary writes in default impl for modifyGet nim-datastore#70
  • Sets proper version for chronos nim-datastore#73

I think nim-datastore is working. PR: codex-storage/nim-datastore#69
