[AMD] Fix slow compilation issue of test_scan_layouts #12807

Workflow file for this run

.github/workflows/integration-tests.yml at a2da0c4

	# AUTOGENERATED by pre-commit, modify the .in file instead.

	# integration-tests.yml.in is used to generate integration-tests.yml by
	# expanding yaml anchors, because github actions don't support them
	# (https://github.com/actions/runner/issues/1182). pre-commit will do this for
	# you automatically.
