[mlir][memref] Fix rollback in test case during `convert-to-llvm` (#135958) This commit is in preparation of the One-Shot Dialect Conversion refactoring, which removes the rollback from the dialect conversion framework. `GenericAtomicRMWOpLowering` (`generic_atomic_rmw`) triggered a rollback in two test cases. The lowering pattern adds additional basic blocks to the enclosing operation, which used to be a `func.func` (now `llvm.func`). Adding a basic block triggers legalization of the op that owns the basic block. This fails when running `--convert-to-llvm="filter-dialects=memref"` because no lowering patterns for the `func` dialect were populated and only `llvm` ops are considered "legal" by the `convert-to-llvm` pass, causing a rollback of the entire `GenericAtomicRMWOpLowering` pattern. Also add extra `CHECK-INTERFACE` to make sure that all test cases are correctly lowered with `--convert-to-llvm="filter-dialects=memref"`.
