  [mlir] Fix memory leaks after #81759 (#82762)

This commit fixes memory leaks that were introduced by #81759. The way
ops and blocks are erased changed slightly.

The leaks were caused by an incorrect implementation of op builders:
blocks must be created with the supplied builder object. Otherwise, they
are not properly tracked by the dialect conversion and can leak during
rollback.
