zpc/unify: Use upstream cmock vanilla

[rzr]

It has been patched with (Added array_as_byte config options ) to support anonymous structures to prevent following failure:

This is introducing technical debt , we might need to find a better solution:

• option 1: upstream the patch (WIP)
  • Origin-SiliconLabs: v2.5.1-74-ga078d10
  • Origin-Upstream: Added array_as_byte config options. ThrowTheSwitch/CMock#503
• option 2: rework S2 to avoid anonymous struct (longer term)
