usdview: Error with Color Management when choosing displays

[mdecaria]

Description of Issue

When using usdview if a Display space is chosen with the new OCIO Config menu, it fails to switch and a python traceback error appears

Steps to Reproduce

1. Ensure OCIO environment is set to a config that contains Displays
2. Open USDView and switch Color Management to OCIO
3. Choose one of the displays listed up the Displays section.
4. See following traceback in terminal:

Traceback (most recent call last):
  File "/path/to/usd/usdView/23.02/lib/python/pxr/Usdviewq/appController.py", line 1752, in setOcioConfig
    if config.hasattr('getDisplayViewColorSpaceName'):
AttributeError: 'PyOpenColorIO.Config' object has no attribute 'hasattr'

hasattr is a python built-in - I would expect the line to be if hasattr(config, "getDisplayViewColorSpaceName"):
