[AIROCMLIR-555] Remove mhal.launch and mhal.await from the codebase

[erizheng-amd]

Motivation

This PR addresses the issue in ticket 555. It removes the dependency on mhal conversions from both Tosa and Linalg by modifying the clone-harness pipeline

Technical Details

• Removed the redundant code and includes for the workaround for mhal instructions
• Modified the clone-harness pipeline from using mhal.launch and mhal.await to func.call
• Modified MHALToGPU.cpp to adapt both mhal and func.call lowering
• Removed support for mhal.launch and mhal.await as they are no longer used
• Updated LIT tests for the change

Test Plan

Tested with check-rocmlir

Test Result

All tests passed

Pull request overview

This PR removes the remaining reliance on mhal.launch/mhal.dependency in MIGraphX-to-{Tosa,Linalg} boundary handling by switching the clone-harness wrapper path to func.call, and updates GPU lowering + LIT tests accordingly.

Changes:

• Update rocmlir-gen clone-harness wrapper generation to use func.call and ensure prefill initialization is inserted for both mhal.launch and func.call paths.
• Remove mhal.launch legality/pattern handling from MIGraphXToTosa and MIGraphXToLinalg boundary conversions.
• Extend MHAL→GPU lowering to handle bufferized func.call to GPU kernels, and update e2e/LIT expectations for the new verification output.
