  [mlir][CSE] Remove the opsToErase container and immediately delete dead ops. (#203702)

This PR removes the `opsToErase` container and immediately erases dead
operations. Since dead ops are deleted on the fly, the value in the
`MemEffectsCache` map now correctly tracks the previous operation of
`toOp`. This change improves the storage efficiency of CSE. Furthermore,
it is part of https://github.com/llvm/llvm-project/pull/180556 and
substantially simplifies the implementation.
