Update on "Refactor layout constraint selection logic"

zou3519 · zou3519 · commit c56c6fde22ee · 2025-05-01T15:11:01.000-07:00
This PR:

- cleans up some existing comments that don't make sense anymore
- hooks up the "custom_op_default_layout_constraint" back (that seems to
have broken)
- cleans up the "lazy registration path" which seems to never get hit
anymore
- adds dislike_padding to nodes that require exact strides

Test Plan:
- tests + CI

disable padding
