  [lldb] Encode operands and arity in Dwarf.def and use them in LLDB. (#94679)

This PR extends Dwarf.def to include the number of operands and the arity (the
number of entries on the DWARF stack).

  - The arity is used in LLDB's DWARF expression evaluator.
  - The number of operands is unused, but is present in the table to avoid
    confusing the arity with the operands. Keeping the latter up to date should
    be straightforward as it maps directly to a table present in the DWARF
    standard.
