  Log Message:
  -----------
  [mlir][SPIR-V] Allow SpecConstantComposite constituents to reference other SpecConstantComposites (#193416)

The verifier for spirv.SpecConstantComposite previously assumed all
constituents were spirv.SpecConstant ops, which caused a crash when
referencing nested spirv.SpecConstantComposite ops

Per the SPIR-V spec (s3.3.7, OpSpecConstantComposite), constituents
"must be the \<id\>s of other specialization constants, constant
declarations, or an OpUndef", which includes OpSpecConstantComposite
