[mlir][spirv] Add basic support for SPV_EXT_replicated_composites (#147067) 
This patch introduces two new ops to the SPIR-V dialect:
- `spirv.EXT.ConstantCompositeReplicate`
- `spirv.EXT.SpecConstantCompositeReplicate`

These ops represent composite constants and specialization constants,
respectively, constructed by replicating a single splat constant across
all elements. They correspond to `SPV_EXT_replicated_composites`
extension instructions:
- `OpConstantCompositeReplicatedEXT`
- `OpSpecConstantCompositeReplicatedEXT`

No transformation to these new ops has been introduced in this patch.

This approach is chosen as per the discussions on RFC
https://discourse.llvm.org/t/rfc-basic-support-for-spv-ext-replicated-composites-in-mlir-spir-v-compile-time-constant-lowering-only/86987
