  [mlir][Transforms] Support `moveOpBefore`/`After` in dialect conversion (#81240)

Add a new rewrite class for "operation movements". This rewrite class
can roll back `moveOpBefore` and `moveOpAfter`.

`RewriterBase::moveOpBefore` and `RewriterBase::moveOpAfter` is no
longer virtual. (The dialect conversion can gather all required
information for rollbacks from listener notifications.)
