  [mlir] Add cross-context checks to the IR verifier (#184627)

Detect IR where result types, operand types, or discardable attribute
values come from a different MLIRContext than the operation itself.
Mixing contexts is a latent use-after-free hazard when one context is
destroyed before the other; the verifier now reports a clear error
instead of silently allowing the invalid IR through.

Three new unit tests in MLIRIRTests cover each scenario.

Fix #61569
