[mlir][assemblyFormat] Fix bug when using AttrSizedOperandSegments trait with only non-buildable operand types

When creating an operation with

  • AttrSizedOperandSegments trait
  • Variadic operands of only non-buildable types
  • assemblyFormat to automatically generate the parser

the builder local variable is used, but never declared.
This adds a fix as well as a test for this case as existing ones use buildable types only.
