5f071fb9 - Add M-tile loop with dispatch capping for Intel Xe2/3-LPG (#28250)

Add M-tile loop with dispatch capping for Intel Xe2/3-LPG (#28250) - Wrap 8x16x16 MatMulNBits(SubgroupMatrix) kernel body in M-tile loop using uniforms.m_tiles_per_wg for tile assignment per workgroup - Cap dispatch_y on Xe2/3-LPG when M > 2k, with occupancy factor 16x - Non-Intel or small-M paths pass m_tiles_per_wg=1 (no behavior change)
