Unknown dimension tests for partitioning and hvx

More tests for unknown dimensions:
- more extensive tests for partitioning
- change existing unknown dimension test to use quantized tensors so
  that it uses the hvx driver when available

Added logging to device selection to make it easier to debug why hvx was
not getting chosen.

TODO: parametrize unknown dimensions test for both floats and quantized
tensors so that it can be used to test other drivers as well
