* Update get_dummy_inputs(...) in T2I-Adapter tests to take image height and width as params.

* Update the T2I-Adapter unit tests to run with the standard number of UNet down blocks so that all T2I-Adapter down blocks get exercised.

* Update the T2I-Adapter down blocks to better match the padding behavior of the UNet.

* Revert "Update the T2I-Adapter unit tests to run with the standard number of UNet down blocks so that all T2I-Adapter down blocks get exercised."

This reverts commit 6d4a060a34415ec973a252944216f4fb8b9926cd.

* Create  utility functions for testing the T2I-Adapter downscaling bahevior.

* (minor) Improve readability with an intermediate named variable.

* Statically parameterize  T2I-Adapter test dimensions rather than generating them dynamically.

* Add docstring for attn_norm_num_groups in UNet2DModel.

* Since the test UNet config uses resnet_time_scale_shift == 'scale_shift', also set attn_norm_num_groups to 32.

* Add test for attn_norm_num_groups to UNet2DModelTests.

* Fix expected slices for slow tests.

* Also fix tolerances for slow tests.
