[RELAX][PASS] Convert layout pass and ops enhanced to support sub indexing (#17568)

srkreddy1238 · web-flow · commit d6413548ab5f · 2025-01-19T13:12:04.000-05:00
Convert layout pass and ops enhanced to support sub indexing

Majority of the operations made compatible with custom layouts.
Incompatible ops will fallback to regular layout.

Conv1D, Conv3D, Pool1D, Pool3D, AdaptiveAvgPool1D, AdaptiveAvgPool3D
are left unchanged now. 2D networks are expected to work now.
