Subject: [PATCH] fix: add const to FixedHash::zero (#5084)

Description
---
Make `FixedHash::zero` a const fn

Motivation and Context
---
A function returning a constant value should be set as const to allow for minor compiled code optimisations. A zero hash is used more often in the DAN layer to indicate a genesis node.

How Has This Been Tested?
---
Minor change, clippy passes
