Colin He c0f73c807d [mlir] Use a container with deterministic iteration order for unrealized materializations (#191323) ...

Iteration over unrealized materializations in DialectConversion is
non-deterministic as the materialization metadata is stored in a
DenseMap. Replacing with a Vector-backed `llvm::MapVector` restores
deterministic behaviour.

This container is iterated for example here:
https://github.com/llvm/llvm-project/blob/main/mlir/lib/Transforms/Utils/DialectConversion.cpp#L3250
