<!--LLVM PR SUMMARY COMMENT-->
@llvm/pr-subscribers-mlir-core
Author: Guray Ozen (grypp)
<details>
<summary>Changes</summary>
This update introduces two new remark emitting policies:
1. `RemarkEmittingPolicyAll`, which emits all remarks,
2. `RemarkEmittingPolicyFinal`, which only emits final remarks after processing.
The `RemarkEngine` is modified to support these policies, allowing for more flexible remark handling based on user configuration.
PR also adds flag to `mlir-opt`
```
--remark-policy=<value> - Specify the policy for remark output.
=all - Print all remarks
=final - Print final remarks
```
