model : Granite MoE shared (#13269)

* feat: Add GGUF conversion for granitemoeshared

Branch: GraniteMoEShared

* feat: hparam and arch plumbing for granitemoeshared

* fix: Split MoE fused tensors for shared experts in conversion

Branch: GraniteMoEShared

* feat: First WIP cut at model arch in cpp

The hparam and architecture plumbing should be correct, but the
implementation of the shared experts seems to still be broken.

* fix: Cleaner (maybe more correct?) splitting for gate/up

* fix: Fix the input to the shared experts

I had misread that the shared experts take the inputs _before_ the standard
MoE layer and was feeding the output of the MoE to the shared experts.

* fix: Avoid architecture-specific checks for Granite MoE Shared

This is a cleaner way that will allow more flexibility in architecture
strings going forward.

* refactor: Split granite architectures out of llm_build_llama

This helps de-clutter the llama-family graph construction and allows
granite to diverge further (in preparation for Granite 4).

NOTE: I removed the granite scale factors from llm_build_deci because they
appear to only be there as copy-paste from llm_build_llama. The HF config
does not seem to set those values:

* fix: Fix compiler warning about uninitialized inp_pos

This should not have been reachable, but it warns on some compliers

* fix: Consolidate GraniteMoEShared into GraniteMoE on the c++ side
