Differential Revision: D88215978

Summary:
This change adds support for the `eliminate_quant_dequant_pairs` flag in the remove clone ops transform. This flag allows users to control whether quantization-dequantization pairs should be eliminated during the clone removal optimization pass.

We need this to control the functionality of this pass in the subsequent diffs.

Differential Revision: D88092217
Summary:
This change fixes an issue where the `RemovePermutesAroundElementwiseOps` pass was not correctly returning the modified flag to indicate whether the graph was changed during the optimization.

The modified flag is crucial for the pass manager to determine if additional passes need to be run or if the optimization has reached a fixed point. Without properly returning this flag, the pass manager may not iterate correctly or may run unnecessary additional passes.

Summary:
This change eliminates code duplication by replacing the local `RemoveCloneOpPass` implementation with the imported `RemoveCloneOpsTransformImported` from the executorch transforms module.

Previously, there were multiple implementations of the clone removal pass scattered across the codebase. This consolidation improves maintainability by ensuring a single source of truth for the clone removal optimization logic.

Differential Revision: D88109862
Summary:
This change reorganizes the pass execution order by moving the remove passes (clone removal, permute removal, etc.) into the iterative section of the pass manager.

Previously, these passes were executed in a single-shot manner. By moving them to the iterative section, the pass manager can now run these optimization passes repeatedly until a fixed point is reached, where no further optimizations can be applied. This is important because removing one operation may enable additional removal opportunities that weren't visible before.
