Arm backend: Add test pipeline for run_transform_for_annotation_pipeline

[SaoirseARM]

Summary

• Adds new test pipeline which runs transform_for_annotation_pipeline on initial exported graph.
• Compares the Initial model against exported model in eager mode to check numerical differences.
• This helps to discover issues in the passes before quantization.
